Benign osteoblastoma is a rare neoplasm of bone tissue most commonly involving the vertebral column and long bones. Occurrence in the calvarium is extremely rare, and no cases in infants have previously been described. We report a case of benign osteoblastoma occurring in the temporal squama of an infant. The clinical features of this type of tumor occurring in the calvarium are briefly discussed.
