Male urethral sarcoma: a case report and literature review / Sarcoma de uretra masculina: relato de caso e revisão de literatura

Urethral tumors are rare and aggressive. They usually affect men (2:1) and occur more commonly in white (85% of cases). Soft tissue sarcomas are a heterogeneous group of tumors that arise from embryonic mesoderm. It represents 1% of all cases of urinary tract malignancies and rarely primary affect the ureter. We report a case of male urethral sarcoma. To date, only two similar cases have been published in literature.

Os tumores de uretra são muito raros e bastante agressivos. Acometem mais frequentemente homens (2:1) e são mais comuns na raça branca (85% dos casos). Os sarcomas de tecidos moles são um grupo heterogêneo de tumores que surgem a partir da mesoderme embrionária e representam 1% de todos os casos de doença maligna urinária, raramente acometendo a uretra primariamente. Relamos aqui um caso extremamente raro de sarcoma uretral masculino com somente dois semelhantes publicados na literatura.

Tumores de la uretra en el adulto / Urethra tumors in adult

Los tumores de uretra, benignos y malignos, en adultos de ambos sexos, son una entidad poco frecuente. La sintomatología, el exámen físico y los estudios complementarios nos permitirán realizar una orientación diagnóstica inicial, pero será la biopsia la que nos dé el diagnóstico definitivo que nos permitirá diferenciar entre un tumor benigno y el cáncer de uretra, cuyo concepto es primordial para la decisión terapéutica ulterior. En general, los tumores uretrales suelen tener una sintomatología común. Los benignos son candidatos para resección quirúrgica, siendo importante considerar aquellas entidades cuyo comportamiento es potencialmente neoplásico ya que deberán tener un seguimiento más estrecho. En cuanto al cáncer uretral hay que considerar que el pronóstico está determinado fundamentalmente por la ubicación anatómica, el tamaño y la profundidad invasora de la neoplasia siendo la histología de menor importancia en la respuesta terapéutica y en la sobrevida. El primer paso terapéutico es el control locorregional quirúrgico de la enfermedad con un margen libre de tumor de 2 cm, debiendo plantearse tratamiento adyuvante con quimioterapia y / o radioterapia en aquellos casos en los que no se pueda conseguir este margen. En casos seleccionados la radioterapia puede ser indicada en monoterapia con intención curativa.

Benign and malignant urethral tumors, in adults of both sexes, are a rare entity. Their symptoms, physical examination, and additional studies will allow us to perform an initial diagnostic approach, but it is the biopsy what will differentiate a benign tumor form cancer. In general, urethral tumors often have common symptoms. Benign tumors can usually be managed with surgical resection, but it is important to consider those entities whose behaviour is potentially neoplastic requiring a closer follow up. The prognosis of urethral cancer is determined mainly by the anatomical location, the size and depth of invasion of the tumor. Histology is of second importance in terms of therapeutic response and survival. The first step in treatment is surgical locoregional control of the disease with a tumor-free margin of 2 cm. Adjuvant chemotherapy and / or radiotherapy should be considered in those cases where this margin cannot be obtained. In selected cases, radiation therapy may be given as monotheraphy with curative intent.
