舌osseous choristomaの1症例

An Osseous Choristoma of the Tongue

I．はじめに

　舌に生じる良性腫瘍のうち骨腫の報告は稀である。本邦においては1938年に牟田ら^2）が最初に報告し，その後数例の症例を知るのみである。われわれは舌に発生した骨腫の1例を経験したのでここに報告する。

　Lingual osseous choristoma is rare. A review of the literature revealed a total of five cases of osteoma since the first case had been reported by Muta and Ogata in 1938 in Japan. The present brief report deals with one additional case of lingual osseous choristoma. A 27-year-old female complained of a discomfort of the throat which occurred after common cold. An osseous choristoma was found pedunculated on the dorsum of the tongue just above the foramen caecum, and it was 1.2cm in diameter and 0.6 in height with a cylindrical shape.
