Heterotopic islands of gastrointestinal mucosa have been observed throughout the entire gastrointestinal tract, from the oral cavity to the rectum, more commonly described in the duodenum, gallbladder, common bile duct, jejunum, Meckel's
diverticulum,
ileum, appendix, colon and rectum. Heterotopic gastrointestinal cysts of the oral cavity are extremely rare lesion. Although to our knowledge, only 29 cases of oral lesion have been reported to date in the world literature.

course
