An Inflamed Cyst with Periosteal Reaction in the Mandible Mimicking Ossifying Fibroma-A Case Report

與骨化性纖維瘤相似之下顎囊腫發炎合併骨膜反應-病例報告

摘要


Impacted mandibular third molars can sometimes lead to the development of dentigerous cysts. In many cases, bone destruction is seen. In some cases, the bone destruction may extend beyond the cortical bone. In the present case, extracortical bone destruction was noted, and newly formed ossifying tissue was noted over the extracortical region. Due to the nature of the lesion, pathological diagnosis was difficult. This case report describes a case of periosteal reaction arising outside the cortical bone of the mandible with a combined cystic lesion of a 12-year-old male child who was treated with surgery. Clinical, radiographical, surgical and histological findings are presented.

下顎阻生第三大臼齒有時會導致含齒囊腫的產生。在許多案例中會產生骨破壞。在部分案例中,骨性破壞可能會延伸至皮質骨之外。本案例中發生延伸至皮質骨外的骨性破壞,並在皮質骨外發現了新生骨組織。病灶之特性使診斷困難。本案為一十二歲男性,產生下顎皮質骨骨外之骨膜反應並有合併之囊腫,後接受外科治療。本文並呈現臨床、放射線、外科以及組織學之發現。
