RESUMO

Os tumores de parede torácicas são relativamente inusitados, representando 1 a 2% de todas as neoplasias, e cerca de 5% das neoplasias torácicas. Sarcomas são tumores raros e com apresentação heterogênea. São divididos em dois grandes grupos: tumores ósseos e de partes moles. A ocorrência na parede torácica é rara, representando 8% de todos os sarcomas. O tratamento de escolha é a ressecção com margens ampliadas e, quando ocorre a invasão de estruturas profundas, a toracectomia é indicada. A reconstrução do arcabouço ósseo é realizada com materiais de síntese, proporcionando estabilidade, e é seguida da reconstrução de partes moles com retalhos musculares, musculocutâneos ou locais ao acaso. Os tumores malignos primários da parede torácica correspondem a menos de 1% de todas as neoplasias e incluem grande variedade de lesões ósseas e de tecidos moles. Os condrossarcomas representam 20% dos tumores primários da parede torácica, sendo que 80% têm origem nas costelas e 20% no esterno.

Chest wall tumors are relatively uncommon, representing 1 to 2% of all neoplasms, and approximately 5% of thoracic neoplasms. Sarcomas are rare tumors with heterogeneous presentation. They are divided into two large groups: bone and soft tissue tumors. Occurrence in the chest wall is rare, representing 8% of all sarcomas. The treatment of choice is resection with wide margins and, when invasion of deep structures occurs, thoracotomy is indicated. The reconstruction of the bone framework is carried out with synthetic materials, providing stability, and is followed by the reconstruction of soft tissues with muscular, musculocutaneous, or random local flaps. Primary malignant tumors of the chest wall account for less than 1% of all neoplasms and include a wide variety of bone and soft tissue lesions. Chondrosarcomas represent 20% of primary tumors of the chest wall, with 80% originating in the ribs and 20% in the sternum.

RESUMO

INTRODUCTION: Postoperative bleeding is one of the main causes of complications in cardiovascular surgery, which highlights the importance of ensuring adequate intraoperative hemostasis, providing a better patient outcome. This study aimed to improve the prevention of postoperative bleeding in the Cardiovascular Surgery Department of the Hospital Estadual Mário Covas (Santo André, Brazil) using an adapted version of the Papworth Haemostasis Checklist to assess the impact of this standardization on bleeding rate, postoperative complications, reoperation, and mortality. METHODS: This is a non-randomized controlled clinical trial, whose non-probabilistic sample consisted of patients undergoing cardiac surgery in the abovementioned service within a two-year interval. The Papworth Haemostasis Checklist was adapted to the Brazilian laboratory parameters and the questions were translated into Portuguese. This checklist was used before the surgeon started the chest wall closure. Patients were followed up until 30 days after surgery. A P-value < 0.05 was considered statistically relevant. RESULTS: This study included 200 patients. After the checklist, a reduction in 24-hour drain output, postoperative complications, and reoperation was observed, although statistical significance was not reached. Finally, there was a significant reduction in the number of deaths (8 vs. 2; P=0.05). CONCLUSION: The use of the adapted checklist in our hospital proved to be an effective intervention to improve the prevention of postoperative bleeding, with a direct impact in the number of deaths in the study period. The reduction in deaths was possible thanks to the reduction in the bleeding rate, postoperative complications, and reoperations for bleeding.

RESUMO

Pectus excavatum(PE) is a congenital chest deformity characterized by deep depression in the sternum. Autologous fat transplantation has been used for aesthetic purposes, mainly on the face, and has recently gained relevance in thoracic and breast surgeries. The present study aims to present a case of mild PE associated with hypomastia. A 24-year-old female patient attended the consultation for breast augmentation due to hypomastia, but the clinical examination also revealed an associated mild PE that the patient did not notice. Surgical planning included breast augmentation and autologous fat transfer. A 260ml silicone breast implant was used, and 250ml of fat was injected in the sternal region and the lower medial contour of the breasts. There were no complications during the 12-month follow-up period. The combination of augmentation mammoplasty and fat transplantation in treating PE deformity proved to be a minimally invasive, good, safe option with high patient satisfaction.

Pectus excavatum (PE) é uma deformidade torácica congênita, caracterizada como uma depressão profunda no esterno. O transplante autólogo de gordura tem sido utilizado para fins estéticos, principalmente na face, e recentemente ganhou relevância nas cirurgias torácica e das mamas. O objetivo do presente estudo é apresentar um caso de PE leve associado a hipomastia. Uma paciente de 24 anos compareceu à consulta para mamoplastia de aumento por hipomastia, mas o exame clínico também revelou um PE leve associado que não foi percebido pela paciente. O planejamento cirúrgico incluiu a mamoplastia de aumento e a transferência de gordura autóloga. Foi utilizado um implante mamário de silicone de 260ml, e uma quantidade total de 250ml de gordura foi injetada na região esternal e no contorno medial inferior das mamas. Não houve complicações durante o período de acompanhamento de 12 meses. A associação de mamoplastia de aumento e transplante de gordura no tratamento da deformidade de PE revelou-se uma opção minimamente invasiva, boa, segura e com alta satisfação da paciente.

RESUMO

Abstract The regional techniques for axillary analgesia are well established. However, few studies have investigated surgical anesthesia. In this report, extensive debridement of axillary necrotizing fasciitis, including the posteromedial region of the right arm, performed under exclusive regional anesthesia in a patient with probable difficult airway is described. The procedure was accomplished under a Serratus Plane Block (SPB) and supraclavicular brachial plexus block, guided by ultrasound, and with venous sedation. We observed satisfactory anesthesia 15 minutes after the intervention, efficient intraoperative pain control and within the following 24 hours. Surgical axilla anesthesia is feasible with the described blocks.

RESUMO

OBJECTIVES: Novel fascial plane blocks may allow early tracheal extubation and discharge from the intensive care unit (ICU). The present study primarily aimed to determine whether fascial plane blocks, in comparison with intravenous analgesia alone, significantly shortened tracheal extubation times in patients undergoing cardiac surgery. The secondary objectives were to compare each block's performance with that of intravenous analgesia alone in terms of the individual tracheal extubation time and length of ICU stay. DESIGN: Retrospective observational study. SETTING: Single-center study. PARTICIPANTS: Patients who underwent cardiac surgery between 2018 and 2019 were identified from a prospective clinical registry. After obtaining ethics approval, the clinical and electronic records of patients undergoing cardiac surgery in 2018 were analyzed. Data of patients receiving fascial plane blocks (erector spinae plane [ESP], pectoral plane I and II [PECs], and serratus anterior plane [SAP] blocks) with intravenous analgesia were compared with those of patients receiving only intravenous analgesia. A propensity score (PS) model was used to control for differences in the baseline characteristics. Adjusted p < 0.05 was considered statistically significant. MEASUREMENTS AND MAIN RESULTS: Of the 589 patients screened, 532 met the inclusion criteria; 404 received a fascial plane block. After PS matching, weighted linear regression revealed that by receiving a block, the predicted extubation time difference was 9.29 hours (b coefficient; 95% CI: -11.98, -6.60; p = 0.022). Similar results were obtained using PS weighting, with a reduction of 7.82 hours (b coefficient; 95% CI: -11.89, -3.75; p < 0.001) in favor of the block. In the fascial-plane-block group, ESP block achieved the best performance. The length of ICU stay decreased by 1.1 days (b coefficient; 95% CI: -1.43, -0.79; p = 0.0001) in the block group. No complications were reported. CONCLUSIONS: Fascial plane block is associated with reduced extubation times and lengths of ICU stay. ESP block achieved the best performance, followed by PECs and SAP blocks. After PS matching, only ESP block reduced the extubation time.

RESUMO

El tumor de Askin o tumor primitivo neuroectodérmico es una neoplasia de células pequeñas redondas que se origina de los tejidos blandos de la pared torácica, probablemente a partir de células embrionarias que migran de la cresta neural. Son tumores muy agresivos que metastatizan rápidamente y de forma diseminada. Clínicamente, los pacientes presentan una masa de tejidos blandos en la pared del tórax que puede cursar o no con dolor. Otras manifestaciones incluyen disnea, tos, pérdida de peso, síndrome de Horner y adenopatías regionales. La radiografía de tórax muestra una masa heterogénea extrapulmonar, por lo general de gran tamaño, que puede opacificar completamente el hemitórax. El pronóstico del tumor de Askin es pobre; sin embargo, el uso combinado de quimioterapia, cirugía y radiación ha mejorado el resultado de forma drástica.

Askin tumor or primitive neuroectodermal tumor is a small round cells' neoplasia, which originates in the chest's soft tissues probably from embryonic cells that migrate from the neural crest. They are very aggressive tumors that metastasize and disseminate quickly. Clinically, patients show a soft tissue mass in the chest that may or may not be accompanied by pain. Other manifestations include dyspnea, cough, weight loss, Horner syndrome and regional lymphadenopathy. Chest radiographies show a usually large extrapulmonary heterogeneous mass, which can completely opacify the hemithorax. The prognosis is poor; however, the combined use of chemotherapy, surgery and radiation has improved results dramatically.

RESUMO

Objective: To evaluate the sagittal tomographic reformatting of the sternum using unpublished radiographic parameters (indexes and angles), comparing them between the different types of pectus, and controls. Methods: 44 patients with pectus deformities and controls underwent chest CT for analysis. The types of pectus were classified into: inferior pectus carinatum (IPC), superior (SPC) and lateral (LPC), and broad (BPE) and localized pectus excavatum (LPE). The following tomographic parameters were created and measured: (1) spine-manubrium-sternum index (SMS); (2) column-sternum index (CSI); (3) manubrium-sternal angle (MSA); (4) inferior manubrium angle (IMA); and (5) inferior sternum angle (ISA). Statistical analysis was performed between the pectus and control groups, and between the different types of pectus. Results: There was a significant difference between: a) pectus excavatum and pectus carinatum when analyzing the SMS, CSI, MSA and ISA indexes. b) LPE and control group for SMS and ISA. c) LPC and LPE, and LPC and BPE for SMS; d) BPE and LPC for CSI; e) IPC and LPE, and IPC and BPE for ISA; f) SPC and LPE, and SPC and BPE for IMA. Conclusion: The radiographic indexes and angles created provided differentiation parameters between patients with different types of pectus, and between these and controls.

RESUMO

El pectus excavatum (PEX) es una deformación de la pared torácica que obedece a una alteración de los cartílagos costales con el consiguiente hundimiento del esternón. Históricamente se clasificaba como un defecto únicamente estético o cosmético, sin embargo en los últimos años se han desarrollado nuevos métodos de estudio para la valoración de las repercusiones de esta patología, y existe cada vez más bibliografía que demuestra importantes repercusiones funcionales. Se realizó una puesta al día de las repercusiones pulmonares de la patología y análisis de los artículos más relevantes de los últimos años. Los síntomas respiratorios son frecuentes, estando presentes en más de la mitad de los pacientes. Se ha demostrado una disminución de la CVF, VEF1 y PEF25%-75%; así como la presencia de un patrón restrictivo y/o obstructivo, un aumento del VR y una alteración de la dinámica respiratoria. Se ha objetivado la afectación del PEX sobre la función pulmonar, determinando categóricamente que esta patología presenta una importante repercusión funcional.

Pectus excavatum (PEX) is a thoracic wall malformation due to an alteration of the costal cartilages with subsequent sinking of the sternum. Historically, it was considered a mere aesthetic or cosmetic defect, however, in recent years, new assessment methods have been developed to evaluate the repercussions of this pathology, and there is an increasing literature that demonstrates important functional consequences. We carried out an update of this pathology's pulmonary repercussions and analyzed the most relevant articles of the recent years. Respiratory symptoms are frequent, present in more than half of the patients. A decrease in FVC, FEV1 and PEF25%-75% has been shown; as well as the presence of a restrictive and/or obstructive pattern, an increase in RV and an alteration in respiratory dynamics. The affectation of PEX on pulmonary function has been objectified, and it has been determined categorically that this pathology has important functional consequences.

RESUMO

OBJECTIVE: This study aims the treatment results of broad pectus excavatum after a long-term follow-up and skeletal maturity. METHODS: Eighty-four children and adolescents with broad-type pectus excavatum were selected for evaluation after treatment with a dynamic orthosis that applies compression to the lower rib projections and prescription of exercises. The broad pectus excavatum was defined as a deformity that the depressed area was greater and covered the area above and below the nipple line. All patients were evaluated for more than 1 year after the end of treatment and skeletal maturity. Post-treatment results were categorized as mild, moderate and severe. Statistic correlations between results and deformity flexibility, deformity severity, and adherence to treatment were assessed. RESULTS: The mean age at the beginning of treatment was 13.3 years, and the follow-up duration was 25.7 months after suspension of orthosis use. Forty-eight percent of patients showed good results. With regular use of orthoses and performance of exercises, this rate increased to 70% (p < 0,001). Mild cases showed more success than severe cases (p = 0,007). Initial flexibility didn't influence the results (p = 0,63). CONCLUSION: Treatment of broad pectus excavatum with orthoses and exercises led to good definitive results in most resilient patients, especially in those with mild deformities. Level of Evidence V, Expert Opinion.

OBJETIVO: Estudar os resultados de longo prazo e com seguimento até a maturidade esquelética do tratamento do pectus excavatum amplo. MÉTODOS: 84 crianças e adolescentes foram tratados com uma órtese que aplicacompressão nas saliências costais inferiores, associada a exercícios específicos. A deformidade foi classificada como ampla quando a depressão tem maior extensão e abrange uma área acima e abaixo da linha mamilar. Os resultados foram categorizados em ruim, regular ou bom, sendo correlacionados estatisticamente com a flexibilidade, a gravidade da deformidade e a adesão ao tratamento, com avaliação um ano após o fim do tratamento e na maturidade esquelética. RESULTADOS: A idade média no início do tratamento foi de 13,7 anos e o seguimento médio foi de 25.7 meses após a suspensão do uso da órtese. 48% dos casos apresentaram sucesso com o tratamento, mas quando os exercícios e o uso da órtese foram regulares, esta taxa aumentou para 70% (p < 0,001). Os casos mais leves tiveram maior sucesso que os de maior gravidade (p = 0,007), mas a flexibilidade inicial não influenciou os resultados (p = 0,63). CONCLUSÃO: O tratamento do pectus excavatum amplo com o uso de órtese e exercícios apresentou bons resultados definitivos na maioria dos pacientes resilientes, em especial nos casos mais leves.

RESUMO

ABSTRACT Introduction: Spontaneous lung herniation (SLH) refers to a protrusion of the lung into an irregular opening through the parietal pleura occurring at the level of the chest wall, diaphragm, or mediastinum. This is a rare entity, and only about 300 cases have been reported worldwide. The following is the first case of SLH reported in Ecuador. Case presentation: This is a 59-year-old male patient with no history of trauma or chronic respiratory diseases. He attended the emergency department due to a 3-day history of hemoptysis, moderate pain in the right hemithorax, edema, submammary hematoma, and a chest wall hernia that was evident during respiratory movements and the Valsalva maneuver. A non-contrast chest CT scan showed free fluid in the right pleural cavity, alveolar patchy infiltrate, protrusion of the medial segment of the middle lobe, and displaced fractures in the 2nd, 3rd, 4th and 5th ribs of the right hemithorax. Pneumonia, pleural effusion, and SLH with right rib fractures were diagnosed. Due to the patient's symptoms, surgical management with right thoracotomy with parasternal incision was decided to reduce the herniated lung parenchyma. Three months after surgery, follow-up imaging scans showed correct disposition of the osteosynthesis material. The patient did not present any discomfort, so follow-up and multidisciplinar^ medical management were continued. Conclusions: SLH is a very rare condition. Its diagnosis is mainly clinical, characterized by chest pain, presence of the hernial defect and sometimes a history of cough, as in this patient. The diagnosis is currently very precise, but treatment options are still under debate. However, surgical intervention is unquestionably the safest choice for achieving the best outcomes due to the rapid improvement of symptoms and the prevention of recurrences.

RESUMEN Introducción. La hernia pulmonar espontánea (HPE) es una protrusión del pulmón en una abertura anormal a través de la pleura parietal que se presenta a nivel de la pared torácica, el diafragma o el mediastino. Esta es una entidad infrecuente de la que solo se han reportado algo más de 300 casos a nivel internacional. A continuación, se presenta el primer caso de HPE reportado en Ecuador. Presentación del caso. Paciente masculino de 59 años sin antecedentes de trauma, ni patologías respiratorias crónicas, quien asistió al servicio de urgencias por cuadro clínico de 3 días de evolución consistente en hemoptisis, dolor en hemi-tórax derecho de moderada intensidad, edema, hematoma a nivel submamario y defecto herniario de la pared torácica que se evidenciaba durante los movimientos respiratorios y la maniobra de Valsalva. La tomografía simple de tórax mostró líquido libre en cavidad pleural derecha, infiltrado alveolar en parche, protrusión del segmento medial del lóbulo medio y fracturas desplazadas en la 2°, 3°, 4° y 5° costilla del hemitórax derecho. Se diagnosticó neumonía, derrame pleural y HPE con fracturas costales derechas. Se decidió dar manejo quirúrgico con toracotomía derecha con incisión paraesternal. Luego de 3 meses de postoperatorio, los controles de imagen mostraron correcta disposición de material de osteosíntesis. El paciente no presentó molestias y continuó en seguimiento y con manejo médico multidisciplinario. Conclusiones. La HPE es una patología infrecuente de diagnóstico principalmente clínico que se caracteriza por dolor torácico, presencia del defecto herniario y en algunas ocasiones antecedente de tos. El diagnóstico actualmente es muy preciso; sin embargo, su tratamiento aún se encuentra en discusión, pero sin dudas la intervención quirúrgica es la opción que aporta mejores resultados debido a la rápida mejoría de los síntomas y a que previene recidivas.

Métodos. Se presenta la experiencia en la clínica CardioVID, Medellín, Colombia, entre los años 2015 y 2019, mediante una revisión retrospectiva de 8 casos sometidos a resección de lesiones benignas de la pared torácica y reconstrucción con material protésico. Resultados. Se encontró una adecuada evolución de los pacientes, con un buen resultado estético y funcional, con adecuado control de la enfermedad, sin reportes de complicaciones ni de recidiva en el seguimiento. Discusión. Una técnica adecuada permite la reconstrucción de estos defectos con complicaciones mínimas y bajas tasas de extracción de prótesis, finalizando con excelentes resultados funcionales y cosméticos. Con nuestra experiencia podemos concluir que la elección adecuada de los pacientes candidatos a manejo quirúrgico, una buena técnica quirúrgica y un personal con experiencia son cruciales para lograr buenos resultados en cuanto a función pulmonar y estética. Además de lograr una sobrevida bajo los parámetros establecidos posterior a lograr una resección R0

Introduction. Surgical management of chest wall lesions with resection and reconstruction with prosthetic material has been increasing, due to advances in surgical techniques and surgeon's experience, as well as innovation and characteristics of prosthetic materials. They allow wide resections of the wall, guaranteeing greater skeletal stability, less alteration of respiratory mechanics, and better aesthetic results.Methods. The experience in the CardioVID clinic, Medellín, Colombia, between the years 2015 and 2019, is presented through a retrospective review of eight cases that underwent resection of benign lesions of the chest wall and reconstruction with prosthetic material.Results. An adequate evolution of the patients was found, with a good aesthetic and functional result, with adequate control of the disease, without reports of complications or recurrence in follow-up.Discussion. An adequate technique allows the reconstruction of these defects with minimal complications and low prosthesis extraction rates, ending with excellent functional and cosmetic results. With our experience, we can conclude that the proper choice of patients who are good candidates for surgical management, a good surgical technique, and an experienced staff are crucial to achieve good results in terms of lung function and aesthetics results, in addition to obtain survival under the established parameters after achieving an R0 resection

RESUMO

Chondrosarcoma is the third most common primary bone malignancy, but its thoracic presentation is unusual compared to the pelvis and extremities. Chest wall chondrosarcomas are difficult to be surgically resected due to their proximity to neurovascular structures. We report the case of a 48-year-old man presenting with a history of chest bulging. Computed tomography showed a lesion of approximately 12 cm in the sagittal axis adjacent to the upper lobe of the left lung, compressing the upper lobar bronchus and causing parenchymal atelectasis. Biopsy revealed chondrosarcoma. The lesion extrinsically compressed the left pectoralis major muscle and invaded the left pectoralis minor muscle. After complete surgical resection, the patient was discharged on postoperative day 20. (AU)

RESUMO

RESUMO: O Tumor de Células Gigantes é uma neoplasia osteolítica benigna, porém agressiva, ricamente vascularizada e com numerosas células gigantes com atividade osteoclástica. Ocorre mais frequentemente nas epífises de ossos longos e raramente acomete as costelas (cerca de 1% dos casos). A apresentação deste tumor em porção anterolateral de arco costal é extremamente rara em comparação com a região posterior. O presente relato descreve o caso de uma paciente que apresentava uma tumoração dolorosa em parede torácica anterolateral esquerda, de crescimento insidioso. Exames de imagem revelaram uma lesão insuflativa em 10º arco costal esquerdo (4,2 x 3,5 cm), com áreas de calcificação interior. A paciente foi submetida a tratamento cirúrgico, com ressecção ampla do tumor, englobando 9º, 10º e 11º arcos costais e uma porção do diafragma. O diagnóstico definitivo de tumor de células gigantes se deu pela imunohistoquímica da peça cirúrgica. Este relato permite fornecer bases para o estudo das possibilidades terapêuticas desta patologia em localizações atípicas, reforçando que a exérese em bloco com margens amplas destes tumores promove uma menor chance de recidiva local.

ABSTRACT: Giant Cell Tumor is a benign but aggressive osteolytic neoplasm, richly vascularized and with numerous giant cells with osteoclastic activity. It often occurs in long bone epiphyses and rarely affects the ribs (about 1% of cases). The presentation of this tumor in the anterolateral portion of the costal arch is extremely rare compared to the posterior region. The present report describes the case of a patient who had a painful tumor on the left anterolateral chest wall, of insidious growth. Imaging exams revealed an insufflating lesion in the 10th left costal arch (4.2 x 3.5 cm), with areas of interior calcification. The patient underwent surgical treatment, with wide resection of the tumor, comprising 9th, 10th and 11th ribs and a portion of the diaphragm. The definitive diagnosis of giant cell tumor was made by immunohistochemistry of the surgical specimen. This report provides a basis for studying the therapeutic possibilities of this pathology in atypical locations, reinforcing that the block excision with wide margins of these tumors promotes a lower chance of local recurrence.

RESUMO

The chest wall chondrosarcoma (CWC) is a rare slowly growing primary tumor of the chest wall with an incidence of <0.5 per million person-years. We present the case of a giant CWC that caused a mass effect on the mediastinum, heart, and lung. Large tumors with thoracic structures compression may be life threatening, and its resection and subsequent chest wall reconstruction represent a significant multidisciplinary surgical challenge. In this case, despite the large tumor dimensions, the preoperative planning-sparing key reconstructive options without compromising the tumor resection-allowed a complete en bloc tumor excision of a grade III chondrosarcoma with negative histologic margins. Successful reconstruction of the large full-thickness chest wall defect, with a latissimus dorsi muscle flap and methyl methacrylate incorporated into a polypropylene mesh in a sandwich fashion, was accomplished. Patient recovery was uneventful with good functional and aesthetic outcomes, and no evidence of recurrence at 1.5 years follow-up. This case report illustrates the main clinical, radiological, and histologic features of a CWC while discussing the surgical goals and highlighting the principles for chest wall reconstruction following extensive resection of a large and rare entity.

RESUMO

Lung abscess is a rare entity in pediatric age, but it generates significant morbidity. Even less frequent is the presence of this with spontaneous drainage to the skin, generating an abscess in the chest wall, reason for consultation, of the present clinical case. Subsequently, the presence of lung abscess with extension to the chest wall without pleural involvement was documented by imaging studies, an extremely rare and unusual entity, with only one case described in the world literature within our reach and in an adult patient.

El absceso pulmonar es una entidad infrecuente en la edad pediátrica, pero que genera una morbilidad importante. Aún menos frecuente es la presencia de este con drenaje espontáneo a piel, generando un absceso en pared torácica, motivo de consulta, del presente caso clínico. Posteriormente y por estudios imagenológicos se documentó la presencia de absceso pulmonar con extensión a pared torácica sin afectación pleural, una entidad extremadamente rara e inusual, con un solo caso descrito en la literatura mundial a nuestro alcance y en un paciente adulto.

RESUMO

La enfermedad de Mondor es una entidad clínica caracterizada por la aparición de una induración palpable similar a un cordón en la superficie del cuerpo. En general es considerada como una tromboflebitis benigna autolimitada que se resuelve en cuatro u ocho semanas sin ningún tratamiento específico. Se presenta un caso de aparición súbita y evolución favorable, espontánea. Se realiza una revisión de la literatura a propósito del mismo.

Mondor's disease is a clinical entity characterized by the appearance of a palpable cord-like lesion on the surface of the body. It is generally considered self-limiting benign thrombophlebitis that resolves in four to eight weeks without any specific treatment. It presents in the case of sudden appearance and favorable, spontaneous evolution. A literature review on the subject is carried out.
