Osseous choristoma of the periodontium

Abstract

Osseous choristoma is a rare, benign lesion of the oral cavity occurring usually on the tongue. It appears as a tumorous mass of normal bony structure with mature cells in an ectopic position. Some lesions represent developmental malformations, whereas others may be reactive lesions, after trauma or chronic irritation. This is the first ever reported case of an osseous choristoma of the periodontium in the lingual aspect of posterior mandible.

Cartilaginous Choristoma of the Gingiva: A Rare Clinical Entity

“…The intraoral choristoma is mainly treated with surgical excision. Recurrences have not been reported in most of the cases with follow-up [ 12 ].…”

Osseous choristoma of submental region: A rare occurrence

“…[5] The present case was unique in itself because choristomas rarely occur in the maxillofacial region, and only 79 cases have been reported so far. [110111213] In the maxillofacial region, they are most frequently located on the dorsum of the tongue near the circumvallate papillae or foramen caecum. On rare occasions, they can be seen in the buccal mucosa, labial mucosa, gingiva, submental region, masseter muscle and submandibular region.…”

“…[1] Several different tissue types may occur in the oral cavity as choristomas. These include gastric mucosa, glial tissue and tumor-like masses of sebaceous glands.…”
