Buccal osseous choristoma in a 5-year-old boy

Choristomas are defined as proliferations of histologically normal tissue located in an abnormal position. Osseous choristomas of oral soft tissue are rare lesions, especially in children, occurring most frequently in the tongue, and less commonly in other sites such as buccal mucosa, palate and alveolar mucosa. It has been suggested that osseous choristomas have developmental or traumatic origins. Definite diagnosis can only be determined after histologic examination, whereupon the treatment of choice is surgical excision. Here we present, what is to our knowledge, a second case of buccal osseous choristoma in a pediatric patient, along with a brief review of the current, pertinent literature.
