Malignant melanoma associated with human immunodeficiency virus infection in three homosexual men.

This report concerns three patients with human immunodeficiency virus (HIV) infection in whom malignant melanoma developed. One patient had metastatic malignant melanoma, one had iris melanoma, and one had a single skin melanoma. All three had lower absolute numbers of CD4+ cells than a control group, and the severity of their disease was inversely proportional to the absolute number of CD4+ cells. This report suggests an association between the immunodeficiency resulting from HIV infection and the development of malignant melanoma.
