　We report here a case of rare form of intestinal Behçet causing only aphthoid ulcers involving a large area but lacking typical ulcers in the ileo-cecal region.

　A 31-year-old housewife visited our hospital complaining of diarrhea, fever, and loss of weight. She had a history of oral aphtha and genital ulcers. Pathological changes due to aphthoid ulcers were noted in the sigmoid colon to the terminal ileum. Her symptoms improved with prednisolone and the lesions disappeared without leaving residual changes such as converging folds.
