Abstract
in English, Portuguese

Small cell carcinoma of the urinary bladder is an extremely aggressive and rare tumor. Even though small cell carcinoma most commonly arises from the lungs there are several reports of small cell carcinoma in extrapulmonary sites. Due to its low frequency there is no well-established management for this disease. We report the case of a 61 year-old man with small cell carcinoma of the bladder who underwent radical cystectomy following neoadjuvant chemotherapy. We also reviewed the literature for the optimal treatment strategy.

O carcinoma de células pequenas da bexiga urinária é um tumor extremamente agressivo e raro. Apesar desses tumores terem como sítio principal o pulmão, existem diversos relatos de carcinoma de pequenas células extrapulmonares. Pela baixa frequência, ainda não existe um tratamento bem estabelecido para essa neoplasia. Relatamos o caso de um homem de 61 anos de idade com carcinoma de células pequenas da bexiga urinária que foi submetido à quimioterapia neoadjuvante seguida de cistectomia radical. Fazemos ainda revisão na literatura em busca dos métodos de maior sucesso para o tratamento.
