Non-acquired immunodeficiency syndrome-defining malignancies in patients infected with human immunodeficiency virus
Acquired Immunodeficiency Syndrome
The finding of younger age at diagnosis in HIV-positive compared to presumed HIV-negative patients may be related in part to earlier detection, as well as preexisting immunosuppression. The specific sites for which a significant difference in age between the HIV-positive and control cases was observed may be related to the mechanisms of immunosurveillance in parts of the body that have ready access to the outside environment. Knowledge of younger age of onset for these malignancies should prompt closer physical examination of these sites by clinicians.
