title: Aggressive osteoblastoma of the temporal bone: a case report and review of the literature.
abstract: Osteoblastoma can take place in any part of the skeleton. Its occurrence in the calvarium is extremely rare. The aggressive form of osteoblastoma is a rare variant. To our knowledge, this is the second case of aggressive osteoblastoma arising in the temporal bone. We report an 18-year-old patient with aggressive osteoblastoma involving the left temporal bone. Computed tomography of temporal bone showed an osteolytic lesion with granular mineralization and mottled ossified density. Permanent histopathologic sections and immunohistochemical stains revealed an aggressive osteoblastoma.
