原発性膀胱腺癌の1例

Abstract

A 41-year-old man, who complained of left dull lumbago, was admitted in January, 1982. Excretory pyelogram showed a non-functioning left kidney with calculi. Cystoscopic examination revealed non-papillary broad base tumor on left trigon and multiple small cystic tumor around it. Retrograde and antegrade pyelogram showed no filling defect that suggested a tumor. Mucinous adenocarcinoma was emonstrated in the biopsy specimen from bladder tumor. The gastrointestinal, respiratory and other genitourinary tracts were examined but no tumor lesion could be found. Therefore, primary adenocarcinoma of the bladder was highly suspected. Firstly, the left kidney was removed in February, 1982. Then in March, 1982 radical cystectomy and lymphadenectomy were done and the urinary tract was reconstructed using an ileal conduit. No urachal remnant was found. Histopathological examination of surgical specimens revealed mucinous adenocarcinoma of the bladder with cystitis cystica and cystitis glandularis.
