Mucoepidermoid penile carcinoma: clinical, histologic, and immunohistochemical characterization of an uncommon neoplasm.

We report a case of a mucoepidermoid penile carcinoma. The specimen was studied by immunohistochemistry and DNA cytometry. Mucoepidermoid and adenosquamous penile carcinoma are exceedingly rare variants of penile cancer, with very little follow-up data available. To evaluate the possible prognostic significance of these differentiation patterns, it is necessary to document more cases of this unusual tumor entity.
