[Metastatic penile tumors: report of three cases]

Metastatic tumor of the penis is uncommon in spite of its rich blood supply, abundant vascular space and the proximity of the pelvic organs which have a high incidence of malignant neoplasms. We report three cases of metastatic penile tumors. The primary sites of these cases were the left ureter, the right kidney and the rectum. We review and discuss sixty two cases collected from the Japanese literature, including our cases.
