Salivary gland heterotopia in the rectum.

Heterotopic tissues in the submucosal region of the gastrointestinal tract are a well-described occurrence. In the rectal region, these most commonly involve gastric-type mucosa. Only rare reports of salivary gland-type tissue presenting as a submucosal rectal heterotopia have been previously reported. This case report reviews the literature and details an occurrence of heterotopic salivary gland-type tissue in the rectal submucosa of a 31-year-old man who presented with intermittent bleeding and a rectal polypoid mass.
