[Lingual osteoma. Apropos of a case]

The authors present a case of osteoma of the tongue. This tumor was discovered without any functional symptom. Surgical resection with histological examination gives the diagnostic. This choristoma is rare, benign and clinically poor. Osteoma of the tongue is a heterotopic bone tissue and his main differential diagnosis are lingual thyroid and thyroglossal cyst. There are several opinions concerning the histogenesis of this choristoma, but an embryological anomaly is probable. Surgical removal of the tumor is curative, without any reported local recurrence.
