Heterotopic gastric mucosa (HGM) of the small bowel is a congenital disorder with a variable clinical presentation. Reported manifestations are gastrointestinal bleeding, intestinal obstruction or perforation, penetration into adjacent organs, and fistulization. Rarely, failure to thrive (FTT) is the clinical manifestation of HGM. We present the case of a baby girl with FTT due to chronic abdominal pain associated with recurrent episodes of abdominal distention, vomiting, and diarrhea. The cause was found to be HGM in the jejunum. The purpose of this paper is to describe this unusual clinical presentation of jejunal HGM. Highlights ? Peptic ulcers caused by heterotopic gastric mucosa (HGM) in the small bowel are rare. ? When present, they usually bleed. ? Chronic abdominal pain and failure to thrive are rare clinical manifestation of HGM in the small intestine.
