膀胱褐色細胞腫の1例

A case of pheochromocytoma of the urinary bladder

　症例は47歳，女性。主訴は排尿時痛および肉眼的血尿。既往に高血圧はなし。膀胱腫瘍の診断にて経尿道的膀胱腫瘍切除術を施行したが，術中高度な血圧上昇をきたし，腫瘍も筋層への浸潤が疑われたため，姑息的切除にとどめた。病理学的検査にて褐色細胞腫と診断され，後日，膀胱部分切除術を施行した。術後11か月の現在，再発の徴候は認められていない。

A 47-year-old female visited us complaining of miction pain and macrohematuria. Cystoscopic examination revealed a non-papilally sessile tumor. We made a diag-nosis of the invasive bladder tumor, and perfomed TUR-BT, radical tumor resection was not possible. Severe hypertension (200 mmHg systolic) with headache appeared during operation. Histologically, the tumor was a pheochromocytoma of the urinary bladder. We subsequently perfomed a partial cystectomy and pelvic lymphadenectomy. She has no clinical evidence of recur-rence for 11 months after the operation.
