Benign Osteoblastoma Involving Maxilla: A Case Report and Review of the Literature

Background. Osteoblastoma is a rare benign tumor. This tumor is characterized by osteoid and bone formation with the presence of numerous osteoblasts. The lesion is more frequently seen in long bones and rarely involves maxilla and mandible. Due to its clinical and histological similarity with other bone tumors such as osteoid osteoma and fibro-osseous lesions, osteoblastoma presents a diagnostic dilemma.Case Report. Very few cases of osteoblastomas involving maxillofacial region have been reported in the literature. This case report involves osteoblastoma involving right maxilla in an 18-year-old male patient. Following detailed clinical examination, radiological interpretation, and histopathological diagnosis, surgical excision was performed. The patient was followed up for a period of 3 years and was disease free.Summary and Conclusion. Benign osteoblastoma involving jaw bones is a rare tumor. There is a close resemblance of this tumor with other lesions such as fibro-osseous lesions and odontogenic tumors and thus faces a diagnostic challenge. Surgical excision with a long-term follow-up gives good prognosis to this lesion—Benign Osteoblastoma.

Osteoblastoma of the nasal septum

Objectives:To present a case of, and to review the literature concerning, osteoblastoma of the nasal cavity, and to demonstrate the importance of considering this rare entity when assessing patients presenting with a nasal septum lesion.Case report:Benign osteoblastoma is a rare tumour, constituting 1 per cent of all bone tumours. Most cases occur in the long bones. Osteoblastoma involving the nasal cavity is rare, with only 10 reported cases in the English-language literature. Most nasal cavity cases originate from the ethmoid sinus and spread to involve the nasal cavity. There are only four reported cases of osteoblastoma originating from the bones of the nasal cavity. We report a case of osteoblastoma originating from the bony nasal septum in a 45-year-old man with a history of recurrent, right-sided epistaxis and nasal obstruction.Conclusion:This is the second report in the English-language literature of osteoblastoma originating from the bony nasal septum.
