Osteoma is a benign osteogenic lesion characterized by the proliferation of compact or cancellous bone. It can be central or peripheral. This lesion commonly arises in the oral and maxillofacial region, but rarely occurs in the zygomatic arch, where only 1 case has been reported. We present a case of peripheral osteoma arising in the articular tubercle of the temporal bone in a 41-year-old woman. Clinical examination revealed a bony, pedunculated, exophytic mass approximately 20×20 mm in size. The clinical diagnosis was osteoma. Under general anesthesia, surgical resection through a preauricular incision was performed. The histopathological diagnosis was peripheral osteoma. The patient remains free of recurrence after 1 year.
