RESUMO
Introdução: O siringomas são tumores anexais benignos com caraterísticas histopatológicas decorrentes dos ductos écrinos, em forma de pápulas amareladas ou cor da pele, de 1-3 mm, comumente na região periorbitária inferior, podendo causar problemas cosméticos importantes. O objetivo do tratamento é melhorar a aparência, através da destruição completa do tumor usando métodos minimamente invasivos e inclusa cirurgia. Existem na literatura múltiplas opções de tratamento com vários graus de sucesso, porém pouco se conhece sobre a eficácia. Em geral, a remoção completa não é bem-sucedida, e têm sido descritos efeitos colaterais, sendo a recorrência o mais frequente. Métodos: Trata-se de uma revisão narrativa de literatura, de publicações científicas no período de 2014-2019. Resultados: Após revisar 45 artigos, e identificar os publicados nos últimos cinco anos que tiveram registro de número de pacientes, descrição de tratamento, escalas de avaliação dos resultados e acompanhamento, foram selecionados seis artigos. Do número total de seis artigos, foram encontrados: uma revisão sistemática, e cinco estudos retrospectivos, sendo um comparativo. Foi designado um número para cada artigo analisado, e coletados o número de pacientes incluídos, tratamento realizado, escalas de avaliação e resultados, complicações e conclusões. Conclusões: Os siringomas periorbitários ainda são um desafio terapêutico, e até agora nenhum tratamento demostrou ser consistentemente eficaz. O laser CO2 continua sendo a primeira escolha de tratamento quando usado fracionado, e a eletrocoagulação intralesional representa uma segunda alternativa com resultados moderados e menor risco de complicações. Novos tratamentos como Laser Erbium Laser Erbium Yttrium Aluminum Garnet, Neodymium-Doped Yttrium Aluminum Garnet e monoterapia com toxina botulínica A poderiam ser boas alternativas. Estudos prospetivos comparativos são necessários.
Introduction: Syringomas are benign adnexal tumors with histopathological characteristics arising from the eccrine ducts, in yellowish or skin-colored papules, 1-3 mm, commonly in the lower periorbital region, which can cause important cosmetic problems. The goal of treatment is to improve appearance by destroying the tumor using minimally invasive methods and including surgery. There are multiple treatment options in the literature with varying degrees of success, but little is known about their effectiveness. Complete removal is unsuccessful, and side effects have been described, recurrence being the most frequent. Methods: This is a narrative review of the literature of scientific publications in the period 2014-2019. Results: After reviewing 45 articles and identifying those published in the last five years that had a record of the number of patients, treatment description, scales of evaluation of results and follow-up, six articles were selected. Of the total number of six articles, we found: a systematic review and five retrospective studies, one being a comparative one. A number was assigned to each article analyzed, and the number of patients included, treatment performed, assessment scales and results, complications and conclusions were collected. Conclusions: Periorbital syringomas are still a therapeutic challenge, and so far, no treatment is consistently effective. The CO2 laser remains the first choice of treatment when used fractionally, and intralesional electrocoagulation represents a second alternative with moderate results and a lower risk of complications. New treatments such as Laser Erbium Laser Erbium Yttrium Aluminum Garnet, Neodymium-Doped Yttrium Aluminum Garnet and botulinum toxin A monotherapy could be good alternatives. Comparative prospective studies are needed.
RESUMO
RESUMEN Los siringomas son tumores anexiales benignos raramente encontrados a nivel vulvar. Se comunica un caso y se realiza una revisión bibliográfica ante la presentación de una mujer de 33 años con múltiples lesiones papulares en labios mayores, de larga data, con diagnóstico anatomopatológico y tratamiento mediante escisión quirúrgica bajo sedación y vaporización con láser CO2.
ABSTRACT Syringomas are benign adnexal tumors rarely reported at the vulvar area. A case is reported and a literature review is performed for the presentation of a 33-yearold woman with multiple papular lesions in labia majora, of long standing, with anatomopathologic diagnosis and treatment by surgical excision under sedation and CO2 laser vaporization.
RESUMO
Syringoma is a benign adnexal tumor of the skin originating from the eccrine sweat duct. There is a wide variety of treatments, and most of the patients receive multiple unsuccessful therapies. The goal of this report intends to describe a novel technique applicable to syringoma with botulinum toxin A. A 61-year-old female patient with localized syringomas in the periocular and upper lip region, with a long-lasting history, treated with botulinum toxin A 46 IU as monotherapy intradermally distributed and a follow-up for 8 months. Our patient displayed a significant improvement of the syringomas. Botulinum toxin A is an efficient and safe technique to treat syringomas.

INTRODUCCIÓN: Los siringomas son tumores benignos derivados de la porción intraepidérmica de los conductos sudoríparos ecrinos. Ocasionalmente pueden iniciar de forma súbita como siringomas eruptivos o localizarse en sitios atípicos que retrasan el diagnóstico por años. La dermatoscopía tiene un rol incipiente en diferenciar siringomas de su extenso diagnóstico diferencial. MÉTODOS: Estudio retrospectivo descriptivo de serie de casos de siringomas de localización atípica. Los datos fueron extraídos de fichas clínicas electrónicas. Todos incluyen dermatoscopía y correlación histopatológica. RESULTADOS: Cinco pacientes. Cuatro hombres y una mujer entre 40 y 79 años de edad con siringomas atípicos: cuatro casos eruptivos y un caso de siringomas vulvares. DISCUSIÓN: Proponemos la dermatoscopía basada en nuestros hallazgos como una herramienta útil con estructuras ovales amarillas y una pseudo-red café clara difusa en su superficie. Estas estructuras amarillas se pueden correlacionar con la proliferación ductal ecrina y el denso estroma en la histopatología. CONCLUSIÓN: Enfatizamos que se debe considerar esta entidad en el diagnóstico diferencial de dermatosis papulares y conocer sus manifestaciones clínicas para optimizar la sospecha diagnóstica.
INTRODUCCTION: Syringomas are common benign tumors, probably of origin derived from the intraepidermal portion of the eccrine sweat ducts. Occasionally they may develop suddenly and extensively as eruptive syringomas or be located in atypical sites delaying the diagnosis for years. Dermoscopy has an incipient role in differentiating syringomas from their extensive differential diagnosis. METHODS: Retrospective descriptive case-series study of atypical location syringomas. Data extraction from clinical history from electronic files. They all include dermoscopy and histopathological correlation. RESULTS: Five patients: Four men and one woman between 40 and 79 years old, with atypical syringomas diagnosis: four eruptive and one vulvar syringomas. DISCUSSION: We propose dermoscopy, based on our findings, as a useful tool to this entity, with its oval yellow structures and a diffuse light-brown network-like structure on its surface. These yellow enlargements may be correlated with the ductal eccrine proliferation and the dense stroma seen in the histopathology. CONCLUSION: We emphasize that they should be considered in the differential diagnosis of papular dermatosis, as they tend to be underdiagnosed, and to know their clinical manifestations to optimize the diagnostic suspicion.

Abstract Collision or contiguous tumors, defined as two or more distinct tumors occurring at one site, are often an unexpected finding and may represent a diagnostic challenge, as clinical and histological presentations do not always coincide. Various combinations of collision tumors have been described with respect to melanocytic lesions, with the most frequently reported being the combination of nevus and basal cell carcinoma. We present an unusual case on the nose involving a melanoma in situ and a clinically-inapparent syringoma, which, to the best of our knowledge, is the first report of this combination.

Introducción: El Siringoma Condroide o tumor mixto es una neoplasia habitualmente benigna que constituye 0,01 por ciento de los tumores primarios de la piel. Es una entidad análoga al tumor mixto (Adenoma Pleomorfo) de glándulas salivales. El diagnóstico es exclusivamente histopatológico. Objetivo: Presentar una paciente con un diagnóstico poco común de Siringoma Condroide benigno, donde se destaca como diagnóstico diferencial entre los tumores de la piel en cabeza y cuello. Presentación de caso: Presentamos el caso de una paciente femenina, de 45 años de edad, quien acude a consulta por presentar un nódulo subcutáneo en la región geniana derecha, que apareció como un pequeño aumento de volumen debajo de la piel, que fue creciendo gradualmente, asintomático, redondeado, bien delimitado, móvil, de consistencia entre suave y firme, de varios meses de evolución, como única lesión. Clínicamente se interpretó como un quiste epidérmico. Su diagnóstico anatomopatológico fue el de Siringoma Condroide benigno o Tumor mixto de la piel. Conclusiones: Resulta un caso interesante debido a la baja frecuencia de presentación de esta lesión. Es importante tener presente esta entidad en el diagnóstico diferencial de los tumores de la piel en cabeza y cuello. A pesar de ser un tumor benigno es necesario el seguimiento del paciente, pues, aunque es muy raro, se han descrito casos con un comportamiento maligno(AU)
Introduction: Chondroid syringoma or mixed tumour is usually a benign neoplasia, constituting 0.01 percent of primary tumours of the skin. This is analogous to mixed tumour (Pleomorphic adenoma) of salivary gland. The diagnosis is only histopathologically. Objective: To present a patient with a diagnosis not very common of chondroid syringoma, where it is highlighted as differential diagnosis among the head and neck skin tumours. Case presentation: Is presented a case of a female patient; 45 years old, that arrived to the consulting room showing a subcutaneous nodule on the right genial region, it appeared as an asymptomatic slow-growing small mass, rounded, well bounded, mobile of soft and firm consistence, of several months of evolution, as a single lesion. The diagnosis was a chondroid syringoma or skin mixed tumour. Conclusions: It is an interesting case because it has a low frequency. It is important bear in mind this entity in the differential diagnosis of head and neck skin tumours. Despite being a benign tumour it is necessary to monitor patients, because even though it is uncommon, some cases have been reported with a malignant behaviour(AU)

Paciente masculino de 81 años de edad que acudió a consulta con un cirujano dentista por presentar una lesión nodular, asintomática, firme y móvil en el labio superior del lado derecho. El sujeto refi rió tener la lesión desde la infancia, pero notó crecimiento lento en el último año. El diagnóstico clínico indicaba un adenoma pleomorfo, por lo que el individuo se sometió a biopsia escisional bajo anestesia local. El espécimen se envió a estudio histopatológico. La evolución del paciente fue satisfactoria, sin reincidencia de la lesión. El examen microscópico reveló la presencia de una neoplasia bien delimitada constituida pormúltiples estructuras ductales pequeñas en la dermis. Estos ductos se encontraban revestidos por dos hileras de células epiteliales planas y contenían cantidades variables de material amorfo en la luz. El estroma presentaba diferenciación condroide.
An 81-year-old male patient consulted a dental surgeon due to his presenting a fi rm, mobile, asymptomatic nodular lesion on the upper lip. The patient stated that he had had the mass since childhood but that it had grown slowly over the course of the previous year. The clinical diagnosis was pleomorphic adenoma, for which reason the patient underwent an excisional biopsy under local anesthesia. The specimen was sent for histopathological examination. The patients progress was satisfactory and there was no recurrence of the lesion. Micro-scopic examination revealed the presence of a well-defi ned neoplasm consisting of multiple small ductal structures located in the dermis. These ducts were lined with two rows of fl attened epithelial cells and contained varying amounts of amorphous material in the lumen. The stroma exhibited chondroid differentiation.

INTRODUCTION: Chondroid syringoma (CS) is a rare cutaneous tumor characterized by mixte epithelial and mesenchymal component. The confident histological diagnosis can be obtained by immuno-histochemistry study. Here we present 10 new cases with their clinico-hystological characteristics. METHODS: The 10 cases were observed between January 2000 and august 2013, in Fort-de-France and Louis-Mourier universitary hospitals. For all the cases a controlled histological study was performed by a dermatopathologist expert and immuno-histochemistry was added. Clinical and immuno-histological data were analyzed. RESULTS: The lesions were almost localized on the face (3/10) and the extremities (3/10). The size was about 1.2 to 5.2cm. Every case was treated by surgery, no malignant case was diagnosed. Histologically, all the 10 cases presented as a well-limited dermic tumor with a mixte epithelial and mesenchymal component. The stroma was myxo-chondroid, and the epithelial component consisted in epithelial cavities lined by one or two cell layers with eccrine (4/10) or apocrine (5/10) features. Immuno-chemistry study reveals positivity for EMA, ACE and CK7 for the internal cells, and positivity for S100 protein and vimentin of the extern cell layer. DISCUSSION: Chondroid syringoma is characterized by a mixte epithelial with eccrine and apocrine cells and a myxo-chondroid stroma. Our study has some clinical and histological particularities (lesions on the extremities, epidermic connecting ). The main differentials diagnoses are the other annexial tumors. The treatment is surgical. CONCLUSION: The histological diagnosis of CS is quite easy, but in case of doubt, immuno-chemistry will help, showing a double mesenchymal and epithelial differentiation.

Syringoma is a benign, adnexal tumor of the eccrine sweat gland ducts. Eruptive syringomas are a rare variant, occurring before or during puberty in most cases. A 57-year-old man was observed in our department, with a 10-year history of multiple brownish papules (1-4mm in diameter), localized on the neck, shoulders, trunk and axillae. The clinical diagnosis was cutaneous mastocytosis. Histopathological examination from a papule in the trunk was compatible with the diagnosis of syringoma. The patient was treated with isotretinoin, without any improvement. The clinical diagnosis of eruptive syringoma is diffi cult and histological examination is crucial for its diagnosis. Long-term morbidity is not associated with syringomas; they are treated for cosmetic reasons with unsatisfactory results.

Los Siringomas son tumoraciones benignas que comprometen el epitelio ductal de la glándula sudorípara ecrina.La etiología es desconocida. El motivo de consulta suele ser por razones estéticas, sin embargo la afección en genitales genera cancerofobia o venerofobia. En la clasificación se incluyen variantes clínicas y asociación a diferentes enfermedades y síndromes.El diagnóstico es clínico e histopatológico. Existen múltiples opciones terapéuticas pero ninguna óptima.En este trabajo presentamos cuatro pacientes con manifestaciones clínicas diferentes y revisión de la literatura.
Syringomas are benign tumors of unknown etiology where the ductal epithelium from sudoriparous eccrine gland is compromised. Main complaint is due to the aesthetic nature, however the genital condition creates fear of cancer or venereal diseases. Classification includes clinical variants and association with different diseases and syndromes. Diagnosis is made by clinical and histopathological examination. Multiple treatment options are proposed with no effective outcome. Four cases with different clinical manifestations are reported and literature review is performed.

O siringoma condróide maligno, também designado tumor misto maligno da pele, é lesão extremamente rara com aproximadamente 40 casos descritos até o presente momento. Trata-se de neoplasia derivada das glândulas sudoríparas que acomete preferencialmente tronco e extremidades distais em pacientes na sexta década e predomina no sexo feminino. Relatamos um caso com os aspectos clínicos e histológicos característicos para familiarizar o patologista com esse diagnóstico, visto que essa neoplasia com freqüência apresenta metástases locais e/ou regionais (cerca de 60 por cento), sobretudo para linfonodos, pulmões e ossos; além disso, possui taxa de mortalidade de aproximadamente 25 por cento após curso evolutivo prolongado.
Malignant chondroid syringoma (malignant mixed tumor of the skin) is an extremely rare tumor. Approximately 40 cases have been described to date. It is a neoplasm originated from sweat gland. The tumor predominantly affects the trunk and distal extremities, arises in the sixth decade and shows a predilection for females. We relate one case with clinical and histopathologic typical features to alert the pathologist to this diagnosis, since this neoplasm has a metastasic rate of approximately 60 percent (lymph nodes, lungs and bones are predominantly affected) and a mortality of roughly 25 percent.
