Embryonal carcinoma of the testis associated with familial adenomatosis coli. Report of a case.

A rare case of embryonal carcinoma of the testis associated with familial adenomatosis coli is reported. The patient may serve as a case to support the hypothesis that familial adenomatosis coli is a systemic or generalized disease with tumorigenicity that is not restricted to the colon and rectum, and that a total colectomy with ileostomy is not always entirely curative.
