Sarcina ventriculi is a gram-positive, obligate anaerobic bacteria first documented in the human gastrointestinal tract in 1842. Sarcina ventriculi are found to be associated with delayed gastric emptying and gastric outlet obstruction Up to date numerous cases of fatal disease have been attributed to this organism in the veterinary literature, but only a few human cases have been documented. Herein we report a case of a 10-year-old girl patient who was diagnosed Celiac disease, selective IgA deficiency and Sarcina ventriculi duodenitis. To the best of our knowledge the association Celiac disease and Sarcina ventriculi duodenitis has not been previously reported in children. Therefore, in the present study we want to draw attention to the importance of a rare coexistance of Celiac disease and Sarcina ventriculi duodenitis.
