Peripheral osteoma of maxilla: A case report

Abstract

Osteoma is a benign osteogenic lesion with a very slow growth, characterized by proliferation of either compact or cancellous bone. Most cases of peripheral osteomas are asymptomatic and produce swelling and asymmetry. Its pathogenesis is unclear but commonly accepted theories propose embryologic, traumatic, or infectious causes. The osteoma may appear in the form of a limited peripheral lesion involving the alveoli or cheek or as a tumoral growth developing inward toward the sinus. Recurrences of osteomas have not been reported in the literature. We report a rare case of maxillary peripheral osteoma with impacted right canine in a 32-year-old female patient.

Cancellous osteoma of maxilla: A rare case report

“…[ 20 ] Osteoma are believed to be relatively uncommon and most of them are compact variety[ 6 7 8 9 12 14 17 18 19 20 21 22 ] and cancellous type of osteoma is very rare. [ 2 3 5 11 23 ] Our patient of peripheral cancellous osteoma recovered without any complication after surgery, and there was no evidence of recurrence during 2 years of follow-up.…”

“…Osteomas are benign osteogenic lesions of bone. [ 1 2 3 ] Histopathologically, osteoma is categorized as compact osteoma and cancellous osteoma, and depending on the location, it can be categorized as peripheral (periosteal) osteoma, central (endosteal) osteoma, and extraskeletal growth. Osteoma cutis is an example of extraskeletal lesion typically located within muscle or the dermis of the skin.…”

External auditory canal osteoma: a case report

“…Osteoma in external auditory canal is uncommon, yet it presents benign lesion which requires only surgical treatment based on complete removal of the lesion and patient follow-up (13). No reports of its malignant transformation have so far been recorded (3). Nevertheless, this entity should be taken into consideration, and distinguished from other possible conditions, especially malignant ones, to adequately inform and treat the patient, but also, to avoid progress of unpleasant symptomatology.…”

“…Osteoma is slowly growing benign tumor composed of well-differentiated osseous tissue (1,2). Etiology is unknown, yet theories discuss congenital origin, embryogenesis, trauma, infection, metaplasia, inflammation, and hormones as possible etiologic factors (1,(3)(4)(5). According to the site of origin, osteomas can be classified to peripheral (ones arising from periosteum), central (those which arise from endosteum) or extraskeletal (ones which appear within muscles) (4,6,7).…”

“…According to the site of origin, osteomas can be classified to peripheral (ones arising from periosteum), central (those which arise from endosteum) or extraskeletal (ones which appear within muscles) (4,6,7). Furthermore, they can be divided into those composed of compact bone, cancellous bone or their combination (3,4). Appearance usually involves craniofacial bones (mandible, and paranasal sinuses), while uncommon locations include: larynx, tongue, neck, middle ear, and temporal bone (6).…”
