Abstract

Osteoblastoma is a benign bone tumour arising from the non-odontogenic epithelium. This tumour predominantly affects the vertebral column and long tubular bones such as the femur and tibia. Herein, we report a case of Osteoblastoma affecting temporal bone. Radiologically, it was thought to be an intraosseous meningioma, hemangioma, or eosinophilic granuloma. Histopathological examination of the tumour showed woven bone arranged in sheets and micro trabecular array, rimmed by a single layer of osteoblast, surrounded by lamellar bone. Intertrabecular spaces were composed of richly vascular fibrotic stroma, consistent with the diagnosis of osteoblastoma.
