上颌骨表皮样囊肿1例

Case Report:Epidermoid Cyst in Maxilla

表皮样囊肿为胚胎发育时期遗留于组织中的上皮细胞发展而形成的囊肿,也可见于损伤、手术等使上皮细胞植入而形成。好发于眼睑、额、鼻、眶外侧、耳下等部位,生长缓慢一般无自觉症状,其治疗方法主要是手术摘除。而发生于颌骨内的表皮样囊肿较少见,本案报道了1例发生于上颌骨的表皮样囊肿,并对该病做了文献回顾。

Epidermoid cyst is a cyst formed by the development of epithelial cells during embryonic development. It can also be formed of epithelial cells implanted by trauma, surgery, and so on. Eyelids, forehead, nose, lateral orbital, and ear are the frequently occurring parts. It grows slowly and generally without symptoms. The main treatment is the surgical re- moval. The cyst occurred in intraosseous epidermoid is rare. In this case, we report an epidermoid cyst in the maxilla and the literature is reviewed.
