Osteoblastoma of the maxilla and mandible: a report of 2 cases and literature review.

ABSTRACT

Osteoblastoma is a very rare primary bone tumour in the maxillofacial region. We report 2 cases of osteoblastoma in the maxilla and mandible, respectively. Histologically, the tumour is composed of small, irregular bony trabeculae and osteoids that are separated by a vascular stroma, and it should be considered in the differential diagnosis of an osteoblastic lesion. Total surgical resection is recommended. The absence of recurrence is largely due to adequate initial treatment.
