혀에 발생한 골종 1예_

Abstract

Noncalcified benign neoplasms are commonly found on the tongue and are usually located on the lateral borders in the anterior two thirds. But, osteoma of the tongue is very rare and usually seen on the foramen cecum of the tongue. Histologic features are usually those of a well-circumscribed mass of vital mature bone beneath the surface epithelium. Possible pathogenesis of osteoma is the ossification of branchial arch remnant or undescended thyroid gland, and metaplastic formation. Recurrence has not been reported following surgical removal. We report this case with a review of literature.
