title: Gastric heterotopia in the rectum. A rare cause of ectopic gastric tissue.
abstract: Gastric heterotopia refers to the discovery of normal gastric tissue at foreign, unexpected sites. It has been described anywhere in the alimentary tract, even in the mediastinum, scrotum, and spinal cord. It is not uncommonly seen in the oesophagus or small intestine. However, large bowel lesions are rare, with the most common location of colonic lesions is the rectum. Although it is a rare entity, it may be the source for significant problems such as rectal bleeding, abdominal pain, deep rectal pain, and malignancy. Here, we report an additional case of gastric heterotopia in the rectum of a 56year old gentleman, and review the literature.
