Culture-proved disseminated cat-scratch disease in acquired immunodeficiency syndrome

A male homosexual (positive for the human immunodeficiency virus) with a recent cat scratch developed fever, epitrochlear and axillary lymphadenopathy, and retinitis. Subsequently, he developed skin (epitheloid hemangioma) and mucosal lesions (Kaposi's sarcoma), multiple liver abscesses, and pleural effusion. Warthin-Starry stains and/or electron micrographs of lymph nodes and skin lesions demonstrated bacilli characteristic of those associated with cat-scratch disease. Cultures of lymph node, pleural fluid, and liver abscess specimens yielded organisms believed to be the causative agent of cat-scratch disease. We believe that disseminated cat-scratch disease may become an indicator of opportunistic infection signaling acquired immunodeficiency syndrome in a patient who is positive for the human immunodeficiency virus.
