The occurrence of heterotopic tissue in the large bowel is relatively rare. The most common type of tissue in such heterotopia is gastric mucosa, but rare cases of pancreatic and salivary tissue are also reported in literature. All cases of salivary choristomas reported in literature arose in the rectum–anal canal region [1–5]. Here we report a submucosal salivary gland choristoma in the sigma ...
