[Bladder cancer associated with von Recklinghausen's disease: a case report]

A 53-year-old man was admitted to our hospital with urinary frequency and miction pain. He had von Recklinghausen's disease with multiple café-au-lait spots and neurofibromatosis. Computed tomography scan and magnetic resonance imaging revealed an invasive bladder tumor 10 cm in diameter, and not metastasis. He was diagnosed as having a bladder tumor (T3a N0 M0 with von Recklinghausen's disease. After balloon occluded arterial infusion (BOAI) chemotherapy, total cystectomy was performed. Pathological diagnosis was transitional cell carcinoma, G3, pT3aN0M0. We reviewed and discussed 97 cases of carcinoma associated with von Recklinghausen's disease reported in the Japanese literature. Only 5 cases of bladder cancer have been reported, including the present case.
