Adenocarcinoma of the urinary bladder presenting as locally advanced endometrial carcinoma. Case report and review of the literature.

BACKGROUND

Carcinoma of the urinary bladder that occurs after urinary diversion is a rare entity. We report a case of an adenocarcinoma arising in a defunctionalized bladder that presented as locally advanced endometrial carcinoma.

CASE: A 77-year-old presented with postmenopausal bleeding and mucous vaginal discharge. She had a prior history of urinary diversion via a Koch pouch. Examination revealed a mass protruding through the cervix and possibly involving the bladder anteriorly. The patient underwent anterior pelvic exenteration for a locally advanced mucinous carcinoma thought to be arising from the uterus and invading into the bladder. Final pathology, however, was consistent with a primary bladder carcinoma.

CONCLUSION

Carcinoma developing in the bladder after urinary diversion presents at an advanced stage and has associated poor overall survival.
