Adenocarcinoma in exstrophy of the bladder--the last case in Scandinavia? A case report and review of literature.

There have been 80 cases of carcinoma in exstrophied bladders described previously. We describe another such case in which the specimen was investigated by mucin histochemical and immunohistochemical techniques. The epithelial lining of the bladder was colonic with colon-specific mucin histochemistry and contents of carcinoembryonic antigen. In many foci there were dysplasia of the colonic epithelium and multiple colonic exophytic adenocarcinomas.
