Picture of Kaposi's Sarcoma Ecchymotic

Ecchymotic Kaposi's sarcoma is a variant of Kaposi's sarcoma in which blood vessels leak blood into the surrounding area. This photo depicts an ecchymotic Kaposi's sarcoma on the back of the hand of a 65-year-old Ashkenazi-Jewish man. The lesion appears as a flat, purple-brownish discoloration (macule) with a 1-cm wide nodule. Ecchymotic Kaposi's sarcoma may be mistaken for bruises. The patient also has onychomycosis on his fingernails.
