Recurrent intraoral osseous choristoma

Submandibular osseous choristoma

“…The histories ranged from 2 months to many years. The patients, at the time of the diagnosis, have been between 8 and 73 years of age, with the majority of them being in their second or third decade (Tohill et al, 1987;Long and Koutnick, 1991;Chou et al, 1991;Ishikawa et al, 1993;Dalkiz et al, 2001). Dates of the case described here are in accordance with those found in the literature.…”

“…Only two cases of recurrence after surgical removal have been published in the English literature. Long and Koutnick (1991) registered a case of recurrence 12 years after surgical excision. That lesion was located in the buccal soft tissue connected to the mandibular ramus.…”

“…The diameters ranged from 5 to 20 mm (Tohill et al, 1987;Long and Koutnick, 1991;Chou et al, 1991;Dalkiz et al, 2001). The histories ranged from 2 months to many years.…”

“…This lesion presents as a focal overgrowth of mature osseous cells located remotely from any original osseous tissue. It is more frequently located in the tongue, but may appear in the buccal mucosa, buccal vestibule, submental region, retromolar pad, masticatory muscles, and in the buccal soft tissue adjacent to the posterior border of the mandibular ramus (Krolls et al, 1971;Davis, 1980;Tohill et al, 1987;Hodder and MacDonald, 1988;Long and Koutnick, 1991;Lin et al, 1998;Psimopoulou and Antoniades, 1998;Dalkiz et al, 2001;Cepeda et al, 2003). In this paper, a case of submandibular osseous choristoma is described, apparently for the first time, in the English literature.…”

Osseous choristoma of the periodontium

“…[3] Osseous choristoma (OC) is a rare tumor composed of normal lamellar bone occurring at a site where bone is not normally found. [1] Choristomas’ occur most frequently in the tongue[4] and less commonly on other sites such as buccal mucosa[56] and alveolar mucosa. [78] The occurrence of such lesions in the periodontium is very rare.…”
