Epidermoid cysts are benign cystic lesions that are usually found in the skin. They can also be found in the organs of the gastrointestinal system. Here, we report a rare case of epidermoid cyst of the appendix which has been published in only three cases in the literature. They can be either congenital or acquired. Congenital epidermoid cysts are related to the inclusion of ectodermal elements at the time of neural groove closure. Acquired cysts are thought to be due to trauma or iatrogenic implantation of the epidermis in locations favorable to growth during surgery. Diagnosis is mainly by histopathological examination of the tissue sample. Complete excision of the cyst with the walls intact is considered curative.
表皮样囊肿是一种通常见于皮肤的良性囊性病变。它们也可在胃肠道系统的器官中发现。在此，我们报告一例罕见的阑尾表皮样囊肿病例，该病例在文献中仅有三例报道。表皮样囊肿可以是先天性的，也可以是后天获得性的。先天性表皮样囊肿与神经沟闭合时外胚层成分的包涵有关。后天性囊肿被认为是由于手术期间在有利于生长的部位发生创伤或表皮的医源性植入所致。诊断主要依靠对组织样本进行组织病理学检查。完整切除囊肿且囊壁完整被认为是治愈性的。
