Peripheral osteoma of the mandible: case report and review of the literature

Solitary Periosteal Osteoma of the Mandible : A Case Report = ورم عظمي سمحاقي منفرد للفك السفلي : تقرير حالة

“…2,4 Sayan et al reported that 22.85% of periosteal osteomas occurred in the mandible as compared to 81.3% reported by Kaplan et al 5,8 Osteomas are classified as: compact/ivory, cancellous/spongy, or mixed on histopathological and clinical grounds. 9,10 Peripheral (periosteal) osteomas are infrequently encountered as solitary lesions. 5 The compact osteoma is comprised of dense, compact bone with some marrow space and osteons.…”

“…The cancellous osteoma shows bony trabeculae and fibrofatty marrow. 10 Kaplan et al reported an increased occurrence of periosteal osteomas between the ages of 15 and 75 years, with a mean age of 25 years. 5 Osteomas do not show any sex predilection; however, cases favouring the cancellous variant in females and the compact form in males have been reported.…”

“…5 Osteomas do not show any sex predilection; however, cases favouring the cancellous variant in females and the compact form in males have been reported. 6,10 The pathogenesis of periosteal osteomas is not well-understood. 3 Kaplan et al proposed three possible aetiologies for periosteal osteomas: developmental, neoplastic and reactive.…”

“…Microscopically, it is composed of areas of endochondral ossification, calcified cartilage and fatty or haematopoetic marrow in the trabecular spaces. 10 Fibrous dysplasia is most commonly confused clinically and radiographically with osteomas. 2 It is usually possible to differentiate the two conditions on the basis of radiographic structure alone.…”

Peripheral Osteoma of Mandible

“…Peripheral osteomas are more frequent in the mandible than the maxilla. Males and females are equally affected, while the age varies between 9-85 years [5]. These lesions usually appear as sessile or pedicled masses.…”
