The cemento-ossifying fibroma (COF) is a mesodermal, non-odontogenic tumour of ectopic multipotential periodontal membrane blast cells. It is aggressive, locally destructive, and has a high recurrence rate. A case report of COF of the petromastoid region is presented. This location has not been described until now. Trauma may act as a trigger to sudden growth of the atopic periodontal tissue. Due to the aggressive behaviour of this tumour and its frequent recurrence radical surgery is needed.
骨化性纤维瘤（COF）是一种由异位多能性牙周膜成纤维细胞形成的中胚层非牙源性肿瘤。它具有侵袭性，可造成局部破坏，且复发率高。本文报告了一例颞骨岩部-乳突区骨化性纤维瘤病例。该部位此前未见报道。创伤可能是异位牙周组织突然生长的诱因。鉴于该肿瘤的侵袭性行为及其频繁复发，需要进行根治性手术。
