Involvement of the penis by rectocolic adenocarcinoma. Report of a case and review of the literature

Abstract

A case report of a rectal carcinoma metastasizing to the penis is reviewed along with a total of 44 similar cases reported in the world literature. Pertinent arguments are presented in favor of yet another possible route of metastases, namely the perineural route, which has not been considered previously. Cavernosography provides valuable information about the extent of tumor spread; used more often, it would lead to recognition of the rare opportunity when an aggressive surgical approach might achieve prolonged survival.
