The term 'choristoma' refers to normal appearing tissue in an abnormal location. We describe a case of choristoma with gastric epithelium of the dorsal tongue in a pediatric patient. Lingual choristomas are uncommon cystic or solid lesions which may demonstrate different types of tissue (e.g. gastric epithelium, respiratory epithelium, osseous and neuroglial tissue) histologically. Choristomas with gastric epithelium, also known as heterotropic gastric mucosa or foregut duplication cysts, are thought to arise from pluripotential cells of the embryonic foregut. They most frequently involve the anterior two-thirds of the tongue. Most patients are asymptomatic, but larger lesions may lead to feeding and breathing difficulties. Pathologic evaluation and surgical excision remain the mainstay of diagnosis and treatment, respectively. The pathologic characteristics of other congenital tongue lesions are also discussed.
