title: Lymph node pathology of acquired immunodeficiency syndrome (AIDS).
abstract: There has been a recent notable increase in the number of patients in the United States seropositive for the human immunodeficiency virus (HIV) and also an increase in the number of otherwise healthy homosexuals with persistent generalized lymphadenopathy (PGL). Lymphoid tissue appears to be a favorite target for the initial viral infection, subsequent opportunistic infections, and associated neoplasms. Therefore, evaluation of PGL is important in understanding the nature of the disease. Biopsies of the acquired immunodeficiency syndrome (AIDS) lymph nodes show a spectrum of abnormal lymphoid proliferations, eventual lymphoid depletion, Kaposi's sarcoma, and malignant lymphoma. Although the individual features of AIDS-related lymphadenopathy may not be specific, the constellation of histologic, immunologic, ultrastructural, and fine needle aspiration findings is characteristic.
