[Adenocarcinoma occurring 37 years after augmentation ileocystoplasty for tuberculous bladder atrophy: report of a case].

A 55-year-old woman was admitted with urinary frequency. She had undergone augmentation ileocystoplasty due to tuberculous bladder atrophy 37 years previously. Cystoscopy revealed a tumor on the posterior wall which had been augmented with the ileum. Partial cystectomy and bladder reconstruction using a segment of ileum and ascending colon were performed. Gross inspection showed a 15 x 10 mm, papillary tumor on the ileal mucosa near the vesico-ileal anastomosis. Histologically, moderately differentiated adenocarcinoma infiltrating into the muscle layer was surrounded by the normal ileal mucosa. She has been free of recurrence for 2 years postoperatively. This is the 8th case of adenocarcinoma following augmentation ileocystoplasty reported in the Japanese literature.
