Chondroblastoma of squamous part of the temporo-parietal region of skull vault: A case report and review of literature

Chondroblastoma of squamous part of temporal bone is a very rare bone tumor. Although most of them are benign, the prognosis is not predictable. A 14-year-old girl presented with recurrent slowly growing mass over the right side of the temporo-parietal region of skull vault. Initial curettage material showed extensive chondroid areas and diagnosed histologically as "enchondroma." Histology of completely excised recurrent mass showed identifiable chondroblastic foci. She was followed up for 3 years and was free from recurrence. Chondroblastomas at very rare sites such as squamous part of temporal bone have variable histology, confusing with other giant cell lesions, variable prognosis, and require prompt diagnosis and complete excision.
