Kaposi's sarcoma in young homosexual men: a histopathologic study with particular reference to lymph node involvement.

Recent reports indicate an increased incidence of Kaposi's sarcoma in young homosexual men. In contrast with the form of the disease seen in the elderly, in which skin involvement is usually confined to the lower extremities, lymph node involvement is rare, and disease progression is relatively slow, Kaposi's sarcoma in young homosexual men is characterized by diffuse skin and lymph node involvement and a fulminant disease course.
