[Rhabdomyosarcoma of the bladder: a case report].

A 15-year-old man with the chief complaint of general fatigue was referred to our hospital on November 11, 1993. Bilateral percutaneous nephrostomy was performed for postrenal anuria. X-ray examinations revealed a huge intrapelvic tumor, and it was histopathologically diagnosed as rhabdomyosarcoma by transrectal needle biopsy. He was initially treated with combination chemotherapy regimen of vincristine, actinomycin-D and cyclophosphamide (VAC therapy). Pelvic exenteration was performed on December 15, 1993. Histopathological findings were alveolar rhabdomyosarcoma with degenerative change and partial necrosis. After the operation, he was given two course of VAC therapy. In May, 1994, brain metastasis occurred, so 4 courses of VAC therapy were administered. For a very short period, neurological symptoms improved, but he died of pneumonia on November 15, 1994.
