title: [A case of acquired immunodeficiency syndrome with ileocecal ulcer].
abstract: We report a case of a patient with acquired immunodeficiency syndrome (AIDS) and ileocecal ulcer. A 31-year-old man was admitted with chief complaints of decreased body weight and abdominal pain. Colonoscopy revealed a round punched-out ulcer on the ileocecal valve. Initially, we suspected entero-Behçet's disease and simple ulcer as the cause of the ileocecal ulcer. However, after histologic examination of tissue biopsies obtained during colonoscopy, we diagnosed the patient as having cytomegalovirus (CMV) enteritis. Based on the patient's white blood cell depletion and CMV enteritis, we performed a human immunodeficiency virus (HIV) antibody test. The test was positive, and the diagnosis of AIDS was established. The number of patients with AIDS has been increasing in Japan; thus, we should consider the possibility of CMV enteritis and AIDS in young adult patients affected by ileocecal ulcer with no notable history.
