Thirteen cases of inflammatory bowel disease suspected to be intestinal tuberculosis are analyzed. In nine, the diagnosis was established from such criteria as caseation necrosis, positive acid-fast stains or cultures of the diseased tissue. In four others, enteric tuberculosis remained a diagnostic possibility as judged by the following criteria: coexistence of the bowel lesion with established tuberculosis elsewhere, a clear response to antituberculous chemotherapy, or typical features on roentgenographic, surgical or histologic examination. The patients with intestinal tuberculosis were not necessarily recent immigrants or poor, nor did they have coexistent active pulmonary disease. Although most exhibited classic features of intestinal tuberculosis, the diagnosis was rarely considered at first. A greater awareness of the entity is needed to avoid confusion between intestinal tuberculosis and Crohn's disease.
