Abstract

Mycobacterium avium complex (MAC) refers to infections caused by one of two nontuberculous mycobacterial species, either M. avium or M. intracellulare and the risk of MAC in patients with human immunodeficiency virus (HIV) infection increases as the CD4+ T cell number declines below 50 cells/mm3. In these patients, fever, night sweats, abdominal pain, weight loss and multiple large retroperitoneal and mesenteric lymph nodes should suggest the diagnosis of MAC infection as well as other known causes of lymphadenitis, including lymphoma, Kaposi's sarcoma, dis-seminated histoplasmosis, cryptococcosis and intraabdominal M. tuberculosis. We report an autopsy case of 55 years-old man with HIV-infection who was diagnosed mesenteric lymphadenitis due to MAC infection as a cause of fever of unknown origin during treatment of the primary central nervous system malignant B-cell lymphoma.
