Résumé
We presented here a rare case of intestinal Behecet's disease simulating Grohn's disease. A 20 year old female complained of recurrence of oral ulcer, genital ulcer, arthralgia, erythema nodosum, abdominal pain and diarrhea, but she had no anal ulcer or anal fistulas. The colonoscopic examanation disclosed diffuse colonie involvement with multiple longitudinal ulcers and inflammatory pseudopolyposis. In hospital, she received ileocecectomy because of distal ilea perforation. Postoperative specimen showed multiple geographic ulcer on ileocecal region, creeping mesenteric fat and thickening of cecal wall. Pathological examination showed perivasculitis, transmural inflammation, fissuring, multiple lymph follicles which are compatible with intestinal Behect's disease. There were no granuloma sugges tive of Crohn's disease. Clinically, the patient met the international criteria of Behcet's disease. Punched out ulcer in the ileocecal region and pathological findings described above confirmed the diagnosis of intestinal Behcet's disease.
