title: [Crohn disease in an AIDS patient].
abstract: We report on a 32-year-old homosexual AIDS patient with Crohn's disease of the ileocecal region. Radiographically the bowel of this region showed thickening of the wall and moderate narrowing of the lumen. Sonography showed an enlargement of the mesenterial lymph nodes. Due to mechanic ileus, ileocecal resection was performed. Histology of the resected bowel segment revealed extensive inflammatory changes throughout the wall and deep ulcerations, corresponding to changes in Crohn's disease. An underlying infection was histologically excluded. The immunologic aspects of Crohn's disease and of AIDS, and the differential diagnoses of Crohn's disease in AIDS patients, are discussed.
