Osteomas in head and neck regions are benign, slow-growing bone neoplasms that usually arised in the paranasal sinuses, maxilla, and mandible. An osteoma in tongue is an extremely rare condition, with fewer than 100 cases reported. It usually presents as a mass mainly located near the foramen cecum. Surgical extirpation is the treatment of choice and the prognosis is excellent. Here we present two cases of lingual osteoma that occurred in a 47-year-old woman and 31-yearold man, respectively. The epidemiology, clinical presentation, and pathogenesis are also discussed.
