Mesonephroid adenocarcinoma of the bladder and urethra: a case report.

Mesonephric or mesonephroid adenocarcinoma of the bladder may be a malignant form of nephrogenic adenoma or nephroid metaplasia. The lesion is rare, and to the best of our knowledge only 9 cases have been reported in the world literature. We report another case of mesonephroid adenocarcinoma of the bladder and urethra which was treated with transurethral resection and subsequent chemotherapy.
