下颌骨内表皮样囊肿1例及文献分析

A case of intramandibular epidermoid cyst and literature analysis

表皮样囊肿为良性瘤样病变,其病因尚不明确,目前认为主要与胚胎时期遗留于组织中以及创伤性植入于组织中的上皮细胞有关。最常见的骨内部位是指骨和颅骨。发生在颌骨内的表皮样囊肿临床上较为罕见,本文报告1例发生在下颌骨内伴有一埋伏牙的表皮样囊肿,并结合相关文献探讨颌骨内表皮样囊肿的病因、临床表现、诊断以及治疗方法。

Epidermoid cysts are generally benign neoplastic lesions,the etiology of which is unclear and is mainly related to epithelial cells left in the tissues during the embryonic period and traumatically implanted in the tissues.The most common intraosseous sites are the phalanges and the skull.Epidermoid cysts occurring in the jaws are clinically rare.In this paper,we report a case of epidermoid cyst occurring in the mandible with embedded teeth and discuss the etiology,clinical manifestations,diagnosis,and treatment of epidermoid cysts in the jaws in the context of the relevant literature.
