Late metastasis of rectal adenocarcinoma to the penis.

Abstract

Rectal cancer metastasising to the penis is an exceptionally rare clinical entity, with less than 80 reported cases. Metastasis to the penis is typically identified in conjunction with widespread metastatic disease and as such is usually associated with a very poor prognosis. We report a case of a man who presented with a metastatic deposit in his penis 15 years after the initial diagnosis of rectal cancer. The patient was initially managed with radical penectomy and perineal urethrostomy formation. This was followed by FOLFIRI chemotherapy regimen when further nodules were identified in his lungs on postoperative imaging. At 20months' follow-up, the patient remains alive and disease-free.
