Kaposi's sarcoma limited to penis treated with cobalt-60 radiotherapy

We report a 78-year-old German man of neither Mediterranean nor Jewish lineage who developed Kaposi's sarcoma localized to his penis. An evaluation for retrovirus infection or other causes of immunosuppression was negative. The nodules responded to radiotherapy with cobalt-60, rapidly involuting. The patient has no evidence of Kaposi's sarcoma for over two years.
