Abstract

Os autores relatam o caso de paciente do sexo feminino, 52 anos, com queixas de hematúria macroscópica e dor pélvica. Foi realizado exame ultrassonográfico, que mostrou massa expansiva em assoalho vesical. A cistoscopia confirmou a presença dessa lesão, sendo realizada biópsia. O exame histológico revelou neoplasia de pequenas células. A análise imuno-histoquímica foi necessária para elucidação diagnóstica. O referido exame demonstrou positividade para os marcadores EWS-FLI1, CD99 e S-100. O diagnóstico foi de tumor neuroectodérmico primitivo. A paciente foi tratada com quimioterapia adjuvante. Depois de sete meses de seguimento, a paciente encontra-se livre de doença.<br>The authors report the case of a 52 year-old woman that presented macroscopic hematuria and pelvic pain. Ultrasound examination was performed, which showed an expansive mass in the bladder floor. A cystoscopy confirmed the presence of this lesion and a biopsy was carried out. Histological analysis showed a small cell neoplasm. The immunohistochemical analysis was required to establish diagnosis. This analysis revealed positivity for EWS-FLI1, CD99 and S-100. The conclusive diagnosis was primitive neuroectodermal tumor. The patient was treated with chemotherapy. After a seven month follow-up period, the patient is disease-free
