Metastatic tumors of the penis.
The penis is a rare site of metastatic neoplasm in spite of its rich blood supply, abundant vascular space, proximity of the pelvic organs and interconnections with the pelvic and vertebral veins as well as lymphatics. The location of primary tumor has varied widely. The urinary bladder, prostate, rectum and rectosigmoid were common primary sites. In our series the bladder was the primary site in 3 patients, prostate in 2, and lung in 1. In 1 patient the metastatic lesion was secondary to lymphoma and in another to leukemia. The mode of metastasis, symptoms, treatment and prognosis are discussed.
