58歳男.膀胱原発の小細胞癌に対して膀胱全摘術と化学療法により術後6ヵ月現在再発を認めていないが,今後の慎重な経過観察を必要とする症例であるWe report a case of small cell carcinoma of the urinary bladder. The patient was a 58-year-old man complaining of gross hematuria. Clinical examination revealed a non-papillary, broad-based tumor on the right bladder wall with a clinical stage of T3a, N0, M0. Neoadjuvant intraarterial infusion chemotherapy with methotrexate, adriamycin and cisplatin was performed, but it was ineffective. Three weeks later we performed a radical cystectomy. The operative specimen of the tumor revealed small cell carcinoma. It was staged pT3aN0M0R0L2V1. Postoperatively, 1 course of adjuvant chemotherapy using cisplatin and etoposide was performed. The patient is alive without any evidence of tumor recurrence at 6 months after operation.
