A Case of Choristoma of Tongue Base / 대한이비인후과학회지

ABSTRACT

The choristoma is a tumor like mass of normal cells in an abnormal location. Intraoral osseous and cartilaginous choristoma is distinctly uncommon. The etiology of choristoma is unknown. It is suggested that the intraoral choristoma is a developmental lesion. Correct diagnosis can be obtained only after histopathologic examination. The treatment of choice is surgical excision. We present a case of osseous and cartilaginous choristoma, occurred on the tongue base and treated by peroral excision, with review of the literatures.
