Delayed nonurothelial metastatic lesions to the penis: a report of two cases

Metastatic lesions to the penis are uncommon and originate most often from other genitourinary primaries. Diagnosis is usually easy, as the primary is already known in most cases. The metastases can very rarely be isolated and delayed for several years after the treatment of the primary tumor. We report two cases of penile metastases from nonurothelial primary lesions. A sigmoid adenocarcinoma was the primary in one case, a renal adenocarcinoma in the other. These two cases were distinctly unusual, as the metastases were delayed for several years after the treatment of the primary. Treatment was palliative with early death in both cases.
