Salivary Gland Choristoma: A Rare Finding at the Gastroesophageal Junction.

A choristoma is a tumor-like outgrowth consisting of heterotopic, histologically mature tissue located at an anatomically unusual part of the body. Salivary gland choristoma at the gastrointestinal junction (GEJ) is an extremely rare entity with only one other case reported in the literature. In this report, we present the case of an 87-year-old female with long-standing gastroesophageal reflux disease (GERD) history who was incidentally found to have salivary gland choristoma at GEJ through an upper endoscopy-guided biopsy.
