title: Disseminated Kaposi's sarcoma not associated with HIV infection in a bisexual man.
abstract: We report a 42-year-old white bisexual man with disseminated Kaposi's sarcoma limited to the skin and gastrointestinal tract. Results of several serum tests for human immunodeficiency virus (HIV) antibodies have been negative. The CD4/CD8 ratio has remained normal, and his Kaposi's sarcoma has had a benign clinical course during 30 months of follow-up. Similar reports of disseminated Kaposi's sarcoma with a benign clinical course in homosexual or bisexual men without demonstrable HIV infection are reviewed. Some cellular immune impairment that might be more prevalent in the homosexual population may be implicated in the pathogenesis of this type of Kaposi's sarcoma.
