The prolonged course of gastrointestinal tuberculosis.

Review of biopsy specimens showed that a patient incorrectly diagnosed 7 years ago as having Crohn's disease actually had histologically proven gastrointestinal tuberculosis of 7 years' duration. It is significant that gastrointestinal tuberculosis and Crohn's disease can mimic each other not only in their clinical, radiologic, and histologic manifestations but also temporally. We discuss the interrelationship between AIDS, tuberculosis, and inflammatory bowel disease.
