We report a 44 years old male, presenting with an eight months history of right lower quadrant pain, diarrhea and weight loss. Colonoscopy showed a proliferative and ulcerated lesion in the cecum, with necrotic areas. Barium enema showed an extensive irregular stenosis with rigidity of cecum and ascending colon. The endoscopic biopsy showed numerous granulomas with giant multinucleated cells of Langhans type. A right colectomy was performed with a good postoperative evolution. Anti tuberculosis treatment was started two weeks later and was well tolerated. The patient is currently asymptomatic after two years of followup.
