title: Malignant melanoma in an HIV-infected man: a case report and literature review.
abstract: Although it is not proven by causative association, several studies indicate that patients with acquired immune deficiency syndrome (AIDS) have a high risk for developing cutaneous malignancies, especially lymphoma and Kaposi's sarcoma. Other malignant cutaneous lesions seen in this patient population include basal-cell carcinoma, squamous-cell cancer, Bowen's disease, and rarely, malignant melanoma. We review the clinical course of a human immunodeficiency virus (HIV)-infected man with a superficial spreading melanoma of the scapula treated with wide local excision. Ten years later, he was diagnosed as having metastatic and widespread disease. By placing our patient's experience in context with other case reports, we sought to determine whether malignant melanoma in the HIV-infected population presents atypically or has a more aggressive natural history. The appearance of malignant melanoma in homosexual men may be coincidental or reflective of the expanding spectrum of HIV-associated diseases. Of the 22 patients reported to have malignant melanoma and HIV, approximately one-third had metastatic disease at the time of initial examination, and those with a decreased CD4+ cell count were most likely to have systemic symptoms. Melanomas among patients with HIV infection were often atypical in appearance, being multiple or metastatic, as is the case in other well-defined immunosuppressed groups. Further epidemiological and clinical studies are required to determine whether melanoma occurs more frequently or is more likely to metastasize in persons with HIV disease. Laboratory investigators must also concentrate on those factors in the setting of HIV disease that may contribute to melanocyte activation. Our patient's fulminant clinical course should alert clinicians to carefully evaluate patients with HIV infection and unusual pigmented cutaneous lesions, or who have a prior history of malignant melanoma.
