Abstract
BackgroundPenile metastases are very rare and arise most frequently from genitourinary cancers. Penile metastases from rectal adenocarcinoma are less common.Case presentationWe report the case of a 47-year-old North Afican man with penile metastases from a rectal adenocarcinoma, which was discovered 4 months after abdominoperineal resection. A penile biopsy was carried out and established the metastatic nature. He underwent palliative chemotherapy treatment. He was still alive 4 months after diagnosis of penile metastases.ConclusionThe prognosis of metastasis to the penis is very poor; the best results have been achieved with surgery but only for lesions where metastasis is limited to the penis.
Highlights
Despite its rich vascularization and the extensive circulatory communication between the neighboring organs, metastatic involvement of the penis is relatively infrequent [1]

Summary
Despite its rich vascularization and the extensive circulatory communication between the neighboring organs, metastatic involvement of the penis is relatively infrequent [1]. The first report of secondary penile malignancy from an adenocarcinoma of the rectum was defined by Eberth in 1870 [4] The prognosis of such metastasis is very poor regardless of the treatment options. Treatment is more often palliative than curative [1] In this case report, we describe a case of penile metastasis secondary to a rectal adenocarcinoma. The. A computed tomography (CT) scan of his abdomen revealed multiple lymph nodes of the mesorectum measuring less than 5 mm but otherwise no overt metastatic disease. A computed tomography (CT) scan of his abdomen revealed multiple lymph nodes of the mesorectum measuring less than 5 mm but otherwise no overt metastatic disease He received radiochemotherapy underwent an abdominoperineal resection; there was no clinical or radiological evidence of distant metastasis at the time of resection. A CT scan was performed that showed: lung metastases; external iliac lymph node metastases; lombo-aortic, celio-mesenteric, and inguinal lymph nodes; penile metastases; and bone metastases (Fig. 2)
