Osseous choristoma of the labial mucosa: A rare case report.

Osseous choristoma is a normal bone tissue in an ectopic position. These are slow growing lesions that are usually completely asymptomatic and only present when there is a disruption in the function of the organ due to its large size as it grows. Definitive diagnosis is obtained only after the histopathological examination. The etiology remains still questionable. The treatment of choice is surgical excision. Here we report a case of choristoma in the lower labial mucosa in a 47-year-old female. [ABSTRACT FROM AUTHOR]
