Heterotopic Gastric Mucosa in the Rectum Treated by Endoscopic Submucosal Dissection: A Case Report

Heterotopic gastric mucosa can be defined as the presence of gastric mucosa outside the stomach and is rarely seen in the rectum. In patients with heterotopic gastric mucosa in the rectum, the best method for diagnosis and treatment is complete excision of the lesion, either surgically or endoscopically, since it can both cause symptoms and have a minimal risk of neoplastic degeneration. We present the case of a 27-year-old female who presented with the complaint of rectal bleeding and itching and underwent endoscopic submucosal dissection after a flat depressed lesion was detected in the rectum.
