EXTRALUMINAL MASS TYPE OF HETEROTOPIC GASTRIC MUCOSA IN THE ILEUM CAUSING HEMORRHAGE
Two infants with heterotopic gastric mucosa in the ileum causing hematochezia are presented. Both showed a hot spot by preoperative abdominal scanning with technetium 99m pertechnetate. Operations revealed that each of these cases had a solid tumor on the antimesenteric side of the ileal serosa. Serial microscopic examination showed that the tumor consisted of gastric fundal gland and there was a small cavity with a few narrow communicating channels between this cavity and gastric mucosa protruding into the ileal cavity. these cases are considered to be the extraluminal mass type of congenital gastric heterotopia.
