RESUMEN
Abstract Background 5-Fluorouracil (5-FU) is a first-line drug to treat cutaneous field cancerization (CFC). There are few clinical trials with topical colchicine (COL). Objective To evaluate the effectiveness of 0.5% COL cream versus 5% 5-FU cream in the treatment of CFC. Method This was a randomized, open, self-controlled clinical trial. Forty-five patients (90 forearms), with three to ten actinic keratoses (AK) on each forearm, used 0.5% COL cream 2×/day for seven days on one forearm, and 5% 5-FU cream 2× /day, for 21 days, on the other forearm. The dosages were defined based on previous clinical trials for each drug. Adverse effects were evaluated after 14 days and outcomes after 90 days of inclusion. The primary outcome was complete AK clearance and the secondary outcomes were: partial clearance (≥50%), reduction in AK count, assessment of the Forearm Photoaging Scale (FPS), AK Severity Score (AKSS), and adverse effects. Results After 90 days, there was complete clearance of AK in 37% (95% CI 24%-49%) and partial clearance in 85% (95% CI 76%-93%) of the forearms treated with 5-FU,versus 17% (95% CI 7%-27%) and 78% (95% CI 66%-88%) for COL (p > 0.07). There was a percentage reduction of 75% in the AK count of the forearms treated with 5-FU (95% CI 66%-83%) and 64% in those treated with COL (95% CI 55%-72%). Regarding FPS and AKSS, there was improvement in both groups, with no difference regarding FPS (p = 0.654), and 5-FU superiority for AKSS (p = 0.012). Study limitations Single-center study. Conclusions 5-FU and COL are effective for treating CFC, with neither showing superiority regarding the reduction in AK counts.
RESUMEN
The aim of this study was to assess, through a systematic review, the status of infrared thermography (IRT) as a diagnostic tool for skin neoplasms of the head and neck region and in order to validate its effectiveness in differentiating benign and malignant lesions. A search was carried out in the LILACS, PubMed/MEDLINE, SCOPUS, Web of Science and EMBASE databases including studies published between 2004 and 2024, written in the Latin-Roman alphabet. Accuracy studies with patients aged 18 years or over presenting benign and malignant lesions in the head and neck region that evaluated the performance of IRT in differentiating these lesions were included. Lesions of mesenchymal origin and studies that did not mention histopathological diagnosis were excluded. The systematic review protocol was registered in the PROSPERO database (CRD42023416079). Reviewers independently analyzed titles, abstracts, and full-texts. After extracting data, the risk of bias of the selected studies was assessed using the QUADAS - 2 tool. Results were narratively synthesized and the certainty of evidence was measured using the GRADE approach. The search resulted in 1,587 records and three studies were included. Only one of the assessed studies used static IRT, while the other two studies used cold thermal stress. All studies had an uncertain risk of bias. In general, studies have shown wide variation in the accuracy of IRT for differentiating between malignant and benign lesions, with a low level of certainty in the evidence for both specificity and sensitivity.

BACKGROUND: Acral melanoma is a subtype with worse outcomes. The Breslow micrometric measurement is the most critical parameter in planning treatment and predicting outcomes. However, for acral lentiginous melanoma, the value of the Breslow thickness is a matter of debate. Depth of Invasion (DOI) is a well-established measure for staging oral squamous cell carcinoma. OBJECTIVE: This study compared DOI and Breslow thickness for predicting acral melanoma outcomes. METHODS: We performed a retrospective cross-sectional study of 71 acral melanoma lesions subjected to sentinel lymph node biopsy at one Brazilian referral center. RESULTS: Cox model univariate analysis showed that both DOI and Breslow thickness predicted melanoma specific survival (HR 1.12; p = 0.0255 and HR 1.144; p = 0.0006, respectively), although Kaplan Meier curve was only significant for Breslow (χ2 = 5.792; p = 0.0161) and not for DOI (χ2 = 0.2556; p = 0.6132). Sentinel lymph node status and presence or absence of ulceration also predicted specific survival in patients with acral melanoma (χ2 = 6.3514; p = 0.0117 and χ2 = 4.2793; p = 0.0386, respectively). Multivariate analysis, however, demonstrated that Breslow depth was the only independent parameter for predicting acral melanoma specific survival (HR 1.144; p = 0.0006). CONCLUSION: Even though Breslow thickness remains the main predictor for survival in acral melanoma, it is not a perfect parameter. The introduction of DOI in this context opens new perspectives for predicting acral melanoma outcomes.

Introdução: O carcinoma basocelular (CBC) de vulva é uma condição rara que corresponde a menos de 0,4% dos casos de CBC e de 2% a 4% das neoplasias de vulva. O CBC de vulva é mais comum entre mulheres brancas, multíparas e na pósmenopausa, especialmente na sétima década de vida. O objetivo é relatar um caso de CBC de vulva no qual discutiram-se os aspectos do diagnóstico e tratamento. Relato de Caso: Mulher de 63 anos de idade, G1P1A0, chega ao consultório em janeiro de 2022 para tratamento de lesão persistente em vulva. Realizou-se biópsia incisional que mostrou tratar-se de provável carcinoma basocelular nodular com invasão da derme. A paciente submeteu-se a uma ressecção do tumor com margens macroscópicas livres e sutura primária. A cirurgia não teve complicações no pré-operatório e no pós-operatório. O histopatológico da peça cirúrgica mostrou tratar-se de carcinoma basocelular nodular com área irregular, plana, branco, medindo 0,7x0,4cm, com as margens laterais distando 7,0 e 5,0mm e profundas, 5,9mm; todas livres. Conclusão: O caso relatado é raro, tendo sido o tratamento de ressecção cirúrgica do CBC de vulva com margens bem-sucedido. Catorze meses após a cirurgia, a paciente encontra-se sem evidências de recidiva local ou regional.
Introduction: Basal cell carcinoma (BCC) of the vulva is a rare condition that accounts for less than 0.4% of BCC cases and 2% to 4% of vulvar neoplasms. BCC of the vulva is more common among white, multiparous and postmenopausal women, especially in the seventh decade of life. The aim is to report a case of BCC of the vulva in which aspects of diagnosis and treatment were discussed. Case report: A 63-year-old woman, G1P1A0, arrives at the office in January 2022 for treatment of a persistent lesion on her vulva. An incisional biopsy was performed and showed that it was likely nodular basal cell carcinoma with invasion of the dermis. The patient underwent tumor resection with free macroscopic margins and primary suture. The surgery had no complications preoperatively or postoperatively. The histopathology of the surgical specimen showed that it was a nodular basal cell carcinoma with an irregular, flat, white area, measuring 0.7x0.4cm, with the lateral margins 7.0 and 5.0mm apart and 5.9mm deep; all free. Conclusion: The reported case is rare, with surgical resection of BCC of the vulva with margins being successful. Fourteen months after surgery, the patient has no evidence of local or regional recurrence.
RESUMEN
O tumor filoide é uma neoplasia fibroepitelial rara que representa 0,3 a 1% de todas as neoplasias mamárias. De acordo com a classificação histopatológica, 12 a 26% são do tipo borderline e aproximadamente 15% desses tumores recorrem após excisão cirúrgica. O tratamento recomendado para todos os tipos de tumor filoide é a excisão cirúrgica, e no caso de tumores gigantes o tratamento deve ser multidisciplinar. Apresentamos o caso de uma mulher de 46 anos com tumor filoide na mama esquerda que recorreu 4 anos após a excisão cirúrgica. O estudo anatomopatológico qualificou-o como tumor gigante e o estudo histopatológico relatou tumor filoide borderline. Foi submetida a excisão cirúrgica com mastectomia esquerda e reconstrução mamária com retalho de grande dorsal mais enxerto de gordura. A paciente apresentou evolução favorável sem recidiva. Concluindo, o tumor filoide gigante borderline recorrente é raro e seu manejo cirúrgico representa um desafio tanto na excisão quanto na reconstrução mamária.
Phyllodes tumor is a rare fibroepithelial neoplasm that represents 0.3 to 1% of all breast neoplasms. According to histopathologic classification, 12 to 26% are borderline type and approximately 15% of these tumors recur after surgical excision. The recommended treatment for all types of phyllodes tumor is surgical excision, and in the case of giant tumors the treatment should be multidisciplinary. We present the case of a 46-yearold woman with a phyllodes tumor in the left breast that recurred 4 years after surgical excision. The anatomopathological study qualified it as a giant tumor and the histopathological study reported a borderline phyllodes tumor. She underwent surgical excision with left mastectomy and breast reconstruction by means of a latissimus dorsi flap plus fat graft. The patient presented a favorable evolution without recurrence. In conclusion, the recurrent giant borderline phyllodes tumor is rare and its surgical management represents a challenge both in breast excision and reconstruction.
RESUMEN
Introdução: Em 1977, a partir dos estudos anatômicos de McCraw et al., passou-se a utilizar o músculo peitoral maior como retalho miocutâneo em ilha. O presente artigo descreve um caso de reconstrução de um defeito da parede anterior do hemitórax direito através do retalho miocutâneo peitoral maior em ilha ipsilateral. Relato do Caso: A.E.S., de 66 anos, sexo masculino foi submetido a ressecção ampla de um carcinoma basocelular infiltrativo recidivante de 13,0 x 8,0cm da região paraesternal direita. O retalho miocutâneo foi transposto através de tunelização subcutânea e as cicatrizes posicionadas em forma de mamaplastia em T invertido. Conclusão: A presente tática cirúrgica é de fácil execução para cirurgiões habituados com reconstrução mamária, apresenta tempo cirúrgico curto e resultado estético-funcional satisfatório.
Introduction: In 1977, based on anatomical studies by McCraw et al., the pectoralis major muscle began to be used as an island myocutaneous flap. The present article describes a case of reconstruction of a defect in the anterior wall of the right hemithorax using the pectoralis major myocutaneous flap in an ipsilateral island. Case Report: AES, 66 years old, male, underwent wide resection of a recurrent infiltrative basal cell carcinoma measuring 13.0 x 8.0 cm in the right parasternal region. The myocutaneous flap was transposed through subcutaneous tunneling and the scars were positioned in the shape of an inverted T mammoplasty. Conclusion: This surgical tactic is easy to perform for surgeons accustomed to breast reconstruction, has a short surgical time, and has satisfactory aesthetic-functional results.
RESUMEN
BACKGROUND: Merkel cell polyomavirus (MCPyV), a human polyomavirus that is unequivocally linked to merkel cell carcinoma (MCC), has been found in association with keratinocytes carcinomas (KC), especially basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC). Nevertheless, there is scarce information about the possible involvement of MCPyV in the development of KC. OBJECTIVES: To assess the presence of MCPyV DNA and Large-T Antigen (LT-Ag) via Polymerase Chain Reaction (PCR) and Immunohistochemistry (IHC) in cases of KC, and to correlate its presence with immunohistochemical markers p16, p53, and ki67, tumor type and subtype, sun-exposed location, and epidemiological data. METHODS: The prevalence of MCPyV DNA, LT-Ag, and immunohistochemical markers p16, p53, and ki67 was assessed by PCR and Immunohistochemistry (IHC) in 127 cases of KC, these results were correlated with tumor type and subtype, sun-exposed location, and epidemiological data. RESULTS: The MCPyV DNA was detected in 42.57% (43 of 101) cases by PCR, the LT-Ag was detected in 16.4% (20 of 122) of cases, p16 in 81.5% (97 of 119), p53 in 66.4% (83 of 125), ki67 in 89% (73 of 82). No correlation between MCPyV LT-Ag and DNA confronted with tumor type, subtype, location site, and immunohistochemical markers was found. A single correlation between the MCPyV LT-Ag and cSCC tumors and peri-tumoral lymphocyte cells was noted. STUDY LIMITATIONS: Further steps need to be taken to better evaluate the MCPyV influence and its possible role in KC carcinogenesis, as the evaluation of the virus genome state, the gene sequence that encodes LT-Ag in the KC tumor cells, and in situ hybridization for viral DNA or RNA in these cells. CONCLUSIONS: Despite the frequent detection of MCPyV in KC, the data available so far does not support the hypothesis of a causal relationship between them.

BACKGROUND: Cutaneous melanoma is a neoplasm with a high mortality rate and risk of metastases to distant organs. The Breslow micrometric measurement is considered the most important factor for evaluating prognosis and management, measured from the granular layer to the deepest portion of the neoplasm. Despite its widespread use, the Breslow thickness measurement has some inaccuracies, such as not considering variations in the thickness of the epidermis in different body locations or when there is ulceration. OBJECTIVE: To evaluate the applicability of a modified Breslow measurement, measured from the basal membrane instead of from the granular layer, in an attempt to predict sentinel lymph node examination outcome and survival of patients with melanoma. METHODS: A retrospective and cross-sectional analysis was carried out based on the evaluation of slides stained with hematoxylin & eosin from 275 cases of melanoma that underwent sentinel lymph node biopsy from 2008 to 2021 at a reference center in Brazil. RESULTS: Analysis of the Cox model to evaluate the impact of the Breslow measurement and the modified Breslow measurement on survival showed that both methods are statistically significant. Logistic regression revealed a significant association between both measurements and the presence of metastasis in sentinel lymph nodes. CONCLUSION: Measuring melanoma depth from the basal membrane (modified Breslow measurement) is capable of predicting survival time and sentinel lymph node outcome, as well as the conventional Breslow measurement.

ABSTRACT BACKGROUND: Healthcare professionals' knowledge, attitudes, and beliefs regarding skin cancer are important for reducing the future impact of the disease. OBJECTIVE: This study evaluated university students' knowledge, attitudes, and beliefs about skin cancer and examined the variables influencing their attitudes and beliefs about the disease. DESIGN AND SETTING: This descriptive cross-sectional study was conducted at the Faculty of Health Sciences at Manisa Celal Bayar University, Manisa, Turkey. METHOD: A total of 960 students participated in this study. Data were collected using the Student Introduction Form, Fitzpatrick Skin Type Scale, Skin Cancer and Sun Knowledge Scale (SCSKS), and Health Belief Model Scale for Skin Cancer (HBMSSC). RESULTS: The mean SCSKS score of the participants was 14.91 ± 4.23. The mean HBSSC scores of the participants were 23.58 ± 7.79 for perceived susceptibility, 14.79 ± 4.59 for perceived severity, 20.64 ± 6.60 for perceived benefits, 15.93 ± 4.09 for perceived barriers, and 21.78 ± 7.14 for self-efficacy. The mean SCSKS total scores of the university students were significantly and positively correlated with the HBMSSC subdimensions. Gender explained 1.58 of the variance in perceived benefits and 1.65 of the variance in self-efficacy, whereas the SCSKS score explained most other variables. CONCLUSION: The students' knowledge of skin cancer and sun protection was moderate. Their attitudes and beliefs regarding skin cancer were unexpected. This study identified students' knowledge of skin cancer and sun protection as the most important variables for improving their attitudes and beliefs about skin cancer.

RESUMEN
ABSTRACT Purpose: To report the clinical findings, treatments, and outcomes in a series of patients with vitreous metastasis from cutaneous melanoma. Methods: This single-center, retrospective, interventional case series included patients with biopsy-confirmed vitreous metastasis from cutaneous melanoma diagnosed between 1997 and 2020. Standard 23- or 25-gauge pars plana vitrectomy was performed for diagnostic sampling. Sclerotomies were treated with double or triple freeze-thaw cryotherapy. Perioperative intravitreal injections of melphalan (32 µg/0.075 mL) were administered, when indicated. Visual acuity, intraocular pressure, and systemic and ocular treatment responses were reported. Results: Five eyes of five patients with unilateral vitreous metastasis from cutaneous melanoma were identified. The median age at diagnosis was 84 (range, 37-88) years. The median follow-up after ophthalmic diagnosis was 28 (8.5-36) months; one patient did not have a follow-up. The initial visual acuity ranged from 20/30 to hand motions. Baseline clinical findings included pigmented or non-pigmented cellular infiltration of the vitreous (5/5), anterior segment (4/5), and retina (3/5). Four patients had secondary glaucoma. Systemic therapy included checkpoint inhibitor immunotherapy (n=3, all with partial/complete response), systemic chemotherapy (n=2), surgical resection (n=3), and radiation (n=2). The median time from primary diagnosis to vitreous metastasis was 2 (2-15) years. One patient had an active systemic disease at the time of vitreous metastasis. The final visual acuity ranged from 20/40 to no light perception. Ophthalmic treatment included vitrectomy in all five patients, intravitreal administration of melphalan in three, and intravitreal administration of methotrexate in one. One patient required enucleation, and histopathology revealed extensive invasion by melanoma cells. Conclusions: Vitreous metastasis from cutaneous melanoma can present as a diffuse infiltration of pigmented or non-pigmented cells into the vitreous and may be misdiagnosed as uveitis. Diagnostic pars plana vitrectomy and periodic intravitreal chemotherapy may be indicated.
RESUMO Objetivo: Descrever os achados clínicos, tratamentos, e desfechos em uma série de pacientes com me tástases vítreas de melanoma cutâneo. Métodos: Série retrospectiva de casos de único centro com intervenção. Pacientes incluídos tiveram seu diagnóstico de MVMC confirmado por biópsia entre 1997 e 2020. Vitrectomia via pars plana com 23 ou 25 gauge foram realizadas para obter espécimens. Esclerotomias foram tratadas com crioterapia em duplo ou triplo congelamento. Injeção intravítrea perioperatória de melfalano (32 ug/0,075 mL) foi administrada quando necessário. Foram relatados acuidade visual, pressão intraocular, resposta terapêutica sistêmica e ocular. Resultados: Cinco olhos de 5 pacientes com metástases vítreas de melanoma cutâneo unilateral foram identificados. Idade média de diagnóstico foi 84 anos (variando de 37-88). Seguimento médio após diagnóstico oftalmológico foi 28 (8,5-36) meses; 1 paciente não teve acompanhamento. Acuidade visual inicial variou de 20/30 a movimentos de mão. Achados clínicos iniciais incluíram infiltração de células pigmentadas e não-pigmentadas no vítreo (5/5), segmento anterior (4/5), e retina (3/5). Quatro pacientes tiveram glaucoma secundário. Tratamento sistêmico incluiu imunoterapia com inibidores da via de sinalização (3 - todos com resposta parcial/completa), quimioterapia sistêmica (2), ressecção cirúrgica (3), e irradiação (2). Intervalo médio entre diagnóstico primário e metástases vítreas foi 2 (2-15) anos. Um paciente teve doença sistêmica ativa simultânea as metástases vítreas. Acuidade visual final variou entre 20/40 e SPL. Tratamento oftalmológico incluiu vitrectomia nos 5 pacientes, melfalano intravítreo em 3 e metotrexato intravítreo em 1. Um paciente precisou de enucleação. A histopatologia revelou invasão celular extensa de melanoma. Conclusões: Metástases vítreas de melanoma cutâneo pode se manifestar como uma infiltração difusa de células pigmentadas e não-pigmentadas no vítreo e erroneamente diagnosticada como uveites. Vitrectomia diagnóstica e quimioterapia intravítrea periódica podem estar indicadas.
RESUMEN
Background: 5-Fluorouracil (5-FU) is a first-line drug to treat cutaneous field cancerization (CFC). There are few clinical trials with topical colchicine (COL). Objective: To evaluate the effectiveness of 0.5% COL cream versus 5% 5-FU cream in the treatment of CFC. Method: This was a randomized, open, self-controlled clinical trial. Forty-five patients (90 forearms), with three to ten actinic keratoses (AK) on each forearm, used 0.5% COL cream 2×/day for seven days on one forearm, and 5% 5-FU cream 2× /day, for 21 days, on the other forearm. The dosages were defined based on previous clinical trials for each drug. Adverse effects were evaluated after 14 days and outcomes after 90 days of inclusion. The primary outcome was complete AK clearance and the secondary outcomes were: partial clearance (≥50%), reduction in AK count, assessment of the Forearm Photoaging Scale (FPS), AK Severity Score (AKSS), and adverse effects. Results: After 90 days, there was complete clearance of AK in 37% (95% CI 24%49%) and partial clearance in 85% (95% CI 76%93%) of the forearms treated with 5-FU,versus 17% (95% CI 7%27%) and 78% (95% CI 66%88%) for COL (p > 0.07). There was a percentage reduction of 75% in the AK count of the forearms treated with 5-FU (95% CI 66%83%) and 64% in those treated with COL (95% CI 55%72%). Regarding FPS and AKSS, there was improvement in both groups, with no difference regarding FPS (p = 0.654), and 5-FU superiority for AKSS (p = 0.012). Study limitations: Single-center study.

Introdução: A reconstrução da região plantar ainda é um dos grandes desafios da cirurgia plástica reconstrutiva. Os tecidos dessa região apresentam características únicas e que são essenciais para a manutenção da funcionalidade do membro. De toda a região plantar, a região do calcanhar é a área de maior sustentação do peso e submetida ao maior impacto. O retalho fasciocutâneo plantar medial é uma das opções reconstrutivas, pois representa tecido semelhante e mantém a sensibilidade para a área receptora. Método: Foi realizado um estudo retrospectivo através da coleta de dados de prontuário de pacientes que realizaram reconstruções da região do calcanhar com retalho plantar medial, no período de julho de 2013 a setembro de 2019. O estudo foi aprovado pelo Comitê de Ética para Análise de Projetos de Pesquisa do HCFMUSP (Número CAAE: 56849422.0.0000.0068). Resultados: A reconstrução de calcanhar após ressecção de melanoma lentiginoso acral foi realizada em 7 pacientes. Complicações cirúrgicas foram observadas em 3 pacientes, sendo que todos eles tinham idade acima de 50 anos e/ou alguma comorbidade associada. Houve 57,1% de complicações, sendo 37,5% relacionadas ao retalho e 12,5% relacionadas à área doadora. Ocorreram 3 necroses totais de retalho (42,9%) e 1 perda total de enxerto na área doadora (14,3%). Conclusão: O retalho plantar medial se apresenta como uma boa alternativa para a realização de reconstruções oncológicas de defeitos na região plantar do pé. Contudo, deve-se ponderar a escolha do paciente ideal e lembrar que a dissecção do seu pedículo vascular não é de fácil execução.
Introduction: Resurfacing the sole is still one of the great challenges of reconstructive plastic surgery. The tissues on the sole of the foot have unique characteristics essential for maintaining the limbs functionality. The heel has the most significant weight support and is subjected to the entire soles greatest impact. The medial plantar artery flap is one of the reconstructive options, as it represents similar tissue and maintains sensitivity to the recipient area. Methods: A retrospective study was performed by collecting data from medical records of patients who underwent reconstructions of the heel with a medial plantar artery flap from July 2013 to September 2019. The study was approved by the Ethics Committee for Analysis of Research Projects of HCFMUSP (CAAE number: 56849422.0.0000.0068). Results: Heel reconstruction was performed in 7 patients after acral lentiginous melanoma excision. Surgical complications were observed in 3 patients, all of whom were aged over 50 years or have associated comorbidity. There were 57.1% of complications, 37.5% related to the flap, and 12.5% related to the donor area. There were three total flap necroses (42.9%) and one total graft loss in the donor area (14.3%). Conclusion: The medial plantar flap presents itself as a good alternative for performing oncological reconstructions of defects in the plantar region of the foot. However, the choice of the ideal patient should be considered and we must remember that the dissection of its vascular pedicle is not easily executed.
RESUMEN
Non-melanoma skin cancer (NMSC) is prevalent in kidney transplant recipients (KTR), related to the immunosuppressive effects of anti-rejection therapy. Sleep disturbances can alter the immune system and enhance oxidative stress, which may increase the risk of carcinogenesis. This study aimed to analyze the quality of life and sleep in KTR with and without NMSC. Participants answered a set of questionnaires, the WHOQOL-bref, the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Berlin Questionnaire and self-reported chronotype. The total sample was distributed in the following groups: KTR with NMSC (n = 42), KTR without NMSC (n = 43) and healthy controls (n = 41). The mean scores of the questionnaires were not statistically significant, except for 3 domains of PSQI (sleep quality, sleep latency and daily consequences of poor sleep). The KTR with NMSC and control group presented worse sleep quality. Worse sleep latency and more daytime consequences were found in KTR groups. All groups had a numerical predominance of low-quality sleep (PSQI) and greater sleepiness (EES). Higher risk of obstructive sleep apnea was not observed and the evening-type chronotype was most frequent. In the WHOQOL, compromised physical domain was observed in KTR. Significant results were reached in few aspects of quality of life and sleep comparing KTR and controls. All groups presented excessive daytime sleepiness and low-sleep quality.

Surgical resection is the gold standard treatment for basal cell carcinomas, although there is literature supporting cryotherapy for low-risk cases. Our aim was to compare the histopathological aspects of recurrent postcryotherapy head and neck cutaneous BCC with de novo tumors, using a case-control study. 51 Recurrent postcryotherapy cases were selected between January 2017 and December 2021 and compared to 132 controls filtered from a consecutive series of de novo head and neck cutaneous BCC operated between January and December 2021. Aggressive variants, multifocality, invasion beyond adipose tissue and higher Clark levels were associated with recurrent cases on multivariate analysis. Previous cryotherapy treatment may have contributed to an increased risk of more aggressive recurrent disease and caution using this treatment modality is advised.

RESUMEN
Abstract Background: Facial nerve dysfunction is the principal postoperative complication related to parotidectomy. Objective: To test the hypothesis that the modified Sunnybrook Facial Grading System (mS-FGS) is superior to the original S-FGS in the assessment of facial nerve function following parotidectomy. Methods: Prospective, longitudinal study evaluating patients with primary or metastatic parotid neoplasms undergoing parotidectomy with facial nerve-sparing between 2016 and 2020. The subjects were assessed twice, on the first postoperative day and at the first outpatient evaluation, 20-30 days post-surgery. Facial assessments were performed using the original and modified (plus showing the lower teeth) versions of the Sunnybrook System and documented by pictures and video recordings. Intra- and inter-rater agreements regarding the assessment of the new expression were analyzed. Results: 101 patients were enrolled. In both steps, the results from the mS-FGS were significantly lower (p < 0.001). Subjects with a history of previous parotidectomy and those who underwent neck dissection had more severe facial nerve impairment. The mandibular marginal branch was the most frequently injured, affecting 68.3% of the patients on the first postoperative day and 52.5% on the first outpatient evaluation. Twenty patients (19.8%) presented an exclusive marginal mandibular branch lesion. The inter-rater agreement of the new expression assessment ranged from substantial to almost perfect. The intra-rater agreement was almost perfect (wk = 0.951). Conclusion: The adoption of the Modified Sunnybrook System, which includes evaluation of the mandibular marginal branch, increases the accuracy of post-parotidectomy facial nerve dysfunction appraisal.
Resumo Antecedentes: A disfunção do nervo facial é a principal complicação pós-operatória relacionada à parotidectomia. Objetivo: Testar a hipótese de que o sistema Sunnybrook de graduação facial modificado (mS-FGS) é superior ao S-FGS original na avaliação da função do nervo facial após parotidectomia. Métodos: Estudo longitudinal prospectivo avaliando o pós-operatório de pacientes com neoplasias parotídeas primárias ou metastáticas, submetidos à parotidectomia com preservação do nervo facial, entre 2016 e 2020. Os indivíduos foram avaliados duas vezes, no primeiro dia de pós-operatório e na primeira avaliação ambulatorial, 20-30 dias após a cirurgia. As avaliações faciais foram realizadas usando as versões original e modificada (que incluem mostrar os dentes inferiores) do sistema Sunnybrook e documentadas por fotos e vídeos. Foram adicionalmente analisadas as concordâncias intra e interexaminadoras da avaliação da nova expressão. Resultados: Cento e um pacientes foram incluídos. Em ambas as etapas, os resultados do mS-FGS foram significativamente menores (p < 0,001). Indivíduos com história de parotidectomia prévia e aqueles submetidos ao esvaziamento cervical apresentaram comprometimento mais grave do nervo facial. O ramo marginal mandibular foi o mais afetado, acometendo 68,3% dos pacientes no primeiro dia de pós-operatório e 52,5% na primeira avaliação ambulatorial. Vinte pacientes (19,8%) apresentaram lesão exclusiva do ramo marginal mandibular. A concordância interexaminadores da avaliação da nova expressão variou de substancial a quase perfeita. A concordância intraexaminador foi quase perfeita (wk = 0,951). Conclusão: A adoção do sistema Sunnybrook modificado, que inclui a análise do ramo marginal mandibular, aumenta a precisão da avaliação da disfunção do nervo facial pós-parotidectomia.
RESUMEN
INTRODUCCIÓN. El gen Tp53 proporciona instrucciones para producir proteína tumoral 53. El Tp53 es un gen supresor tumoral que protege el ciclo celular, reparando el ADN o activando la apoptosis. Es clave en la carcinogénesis del carcinoma basocelular, patología que cobra relevancia en Ecuador, debido a su latitud y altitud, factores que determinan un mayor daño por exposición a radiación ultravioleta y por ende para carcinoma basocelular. Estudios sugieren que la inmunoexpresión de la proteína tumoral 53 podría ser un predictor de recurrencia en esta neoplasia. OBJETIVO. Determinar si el grado de expresividad de especies mutadas de proteína tumoral 53 en pacientes con carcinoma basocelular es una variable que tiene relación con la recurrencia y agresividad en los diferentes subtipos histológicos. MATERIALES Y MÉTODOS. Estudio de revisión bibliográfica de diferentes artículos científicos publicados en revistas indexadas y bases de datos durante los últimos diez años: ElSevier, Medigraphic, PubMed, Redalyc, ResearchGate, ScienceDirect, SpringerLink, Cochrane Database of Systematic Reviews. RESULTADOS. Se obtuvieron 104 resultados de los cuales se seleccionaron 50 artículos científicos que incluyeron revisiones sistemáticas, meta-análisis, artículos originales y reportes de casos en idiomas español e inglés. CONCLUSIÓN. Tp53 se encuentra mutado en más del 50% de carcinomas basocelulares y tiene un rol clave en su carcinogénesis. La inmunoexpresión aberrante de proteína tumoral 53 es un marcador de riesgo de recurrencia y agresividad en carcinoma basocelular, como lo indican los artículos revisados. Sin embargo, se requiere estudios locales que establezcan el verdadero valor de proteína tumoral 53 como marcador de recurrencia y/o agresividad en la población ecuatoriana.
INTRODUCTION. The Tp53 gene provides instructions to produce tumor protein 53. Tp53 is a tumor suppressor gene that protects the cell cycle, repairing DNA or activating apoptosis. It is key in the carcinogenesis of basal cell carcinoma, a pathology that is relevant in Ecuador, due to its latitude and altitude, factors that determine greater damage by exposure to ultraviolet radiation and therefore for basal cell carcinoma. Studies suggest that the immunoexpression of tumor protein 53 could be a predictor of recurrence in this neoplasm. OBJECTIVE. To determine whether the degree of expression of mutated species of tumor protein 53 in patients with basal cell carcinoma is a variable related to recurrence and aggressiveness in the different histologic subtypes. MATERIALS AND METHODS. Bibliographic review study of different scientific articles published in indexed journals and databases during the last ten years: El-Sevier, Medigraphic, PubMed, Redalyc, ResearchGate, ScienceDirect, SpringerLink, Cochrane Database of Systematic Reviews. RESULTS. A total of 104 results were obtained from which 50 scientific articles were selected, including systematic reviews, meta-analyses, original articles and case reports in Spanish and English. CONCLUSIONS. Tp53 is mutated in more than 50% of basal cell carcinomas and plays a key role in their carcinogenesis. Aberrant immunoexpression of tumor protein 53 is a risk marker for recurrence and aggressiveness in basal cell carcinoma, as indicated by the reviewed articles. However, local studies are required to establish the true value of tumor protein 53 as a marker of recurrence and/or aggressiveness in the Ecuadorian population.

O dermatofibrossarcoma é um câncer raro que apresenta padrão de crescimento lento e invasão tecidual agressiva. O tratamento para esta condição envolve intervenção cirúrgica com o objetivo de obter margens livres. Neste caso particular, temos um homem de 60 anos que apresentava uma massa na região da glabela que foi extirpada duas vezes sob anestesia local em outro serviço. Os resultados de ambas as biópsias indicaram dermatofibroma. No entanto, o paciente apresentou nova recidiva, que durante a análise imuno-histoquímica da excisão inicial revelou tratar-se de dermatofibrossarcoma. Como resultado, uma ampla excisão foi realizada até que margens negativas fossem obtidas ao exame de congelação. Além disso, um retalho frontal foi empregado no procedimento para reconstrução do defeito cirúrgico. O resultado do tratamento foi considerado bem-sucedido, sem complicações.
Dermatofibrosarcoma is a rare cancer with a slow growth pattern and aggressive tissue invasion. The treatment for this condition involves surgical intervention to achieve clear margins. In this particular case, we have a 60-year-old man who had a mass in the glabella area that was excised twice under local anesthesia at a different facility. The results of both biopsies indicated dermatofibroma. However, the patient experienced a new recurrence, and during the immunohistochemistry analysis of the initial excision, it was revealed to be dermatofibrosarcoma. As a result, a broad excision was performed until negative margins were obtained based on frozen sections. Additionally, a frontal flap was employed to reconstruct the surgical defect. The outcome of the treatment was deemed successful, without complications.
RESUMEN
Algunos pacientes en la tercera edad desarrollan con frecuencia diversas enfermedades, entre ellas se encuentra el cáncer de piel y la predisposición a la aparición de tumores, tanto en los párpados como en la conjuntiva. Entre los tumores epiteliales malignos se destacan: el carcinoma basocelular y el carcinoma epidermoide; con menor frecuencia, el carcinoma de células de Meibomio y el melanoma palpebral, y raramente, el carcinoma de células de Merkel. Por esta causa, se realizó la presentación de un caso clínico que recibió tratamiento en el Servicio de Cirugía Plástica del Hospital Vladimir Ilich Lenin, de Holguín, al cual se le aplicó la técnica de Mustardé por presentar tumor del párpado inferior. El objetivo fue presentar un paciente con reconstrucción palpebral postumorectomía y mostrar su resultado funcional y estético postoperatorio. Este caso evolucionó satisfactoriamente, sin aparición de complicaciones transoperatorias o postoperatorias.
Some elderly patients frequently develop various diseases, including skin cancer as well as a predisposition to the appearance of tumours, both in the eyelids and conjunctiva. Basal cell carcinoma and epidermoid carcinoma stand out among the malignant epithelial lesions; meibomian cell carcinoma and palpebral melanoma which are less common, and Merkel cell carcinoma rarely known. We present a male patient who received treatment in the plastic surgery service at "Vladimir Ilich Lenin" Hospital, in Holguín, to which Mustardé technique was applied for a tumour of the lower eyelid. An eyelid reconstruction was performed after lumpectomy which allowed us to show a postoperative functional and aesthetic result. This case evolved satisfactorily, without the appearance of intraoperative or postoperative complications.
