Exclusive penile Kaposi's sarcoma: report of an HIV‐negative man successfully treated with radiotherapy

Kaposi's sarcoma (KS) is a rare neoplasm of endovascular cells with multifocal origin. The exact nature of the disease is not clear, but current data support the notion that KS is a vascular hyperplasia with a tight link to human herpesvirus 8 (HHV‐8) infection. Classic KS occurs primarily on the lower extremities in elderly men living in the Mediterranean region. Penile involvement has rarely been reported in non‐human immune deficiency virus (HIV) patients. Herein we present a 71‐year‐old HIV‐negative man with isolated KS on the penis who was treated successfully with radiotherapy. A review of the literature is also presented.
