Penile Metastasis of Rectum Adenocarcinoma

Metastatic penile lesions are rare. Less than 500 cases have been reported in the literature. The primary source in approximately 70% of these rare cases is the genitourinary system. Cases originating from the lungs, bone, and rectum have been reported less frequently. In only 56 of these, the primary site was the rectum. There are no typical symptoms of metastatic penile lesions. Patients generally present with a hard, immobile, painless mass or nodule. The most effective imaging method is currently magnetic resonance imaging. Various palliative or curative treatment methods such as chemotherapy, total penectomy and radiotherapy have been reported in the literature. However, patient prognosis is still poor. The reported median survival in these patients is approximately nine months. This paper aims to present a penile metastasis occurring in a patient with known rectum adenocarcinoma, together with the imaging findings.
