Heterotopic gastric mucosa has been described in all levels of the gastrointestinal tract. However, gastric heterotopia of the rectum is a rare finding. It is usually reported along with polyp located in the rectum between 5 and 8 cm from the anal verge. The most common symptom is painless rectal bleeding, and non-specific gastrointestinal symptoms may also be presented. We report an incidentally found case of a 46-year-old man without any gastrointestinal symptoms. The pathology showed gastric mucosa and squamous epithelium and focal intestinal metaplasia. This finding could be a clue as to the origins of the heterotopic gastric mucosa. Although there are no guidelines for treatment or the follow-up period, regular endoscopic surveillance is necessary for gastric cancer screening.
