چکیده
Dermoid cysts are rare developmental teratomatous lesions composed of ectodermally derived stratified squamous epithelium and mesodermally derived skin adnexal structures. Although several theories have been postulated, the pathogenesis of dermoid cysts and teratomatous lesions in general is unclear. Ovary is the most frequent affected organ, but it can occur in the mediastinum retroperitoneum, testis, and even in the liver. Presacral dermoid cyst accounts for small percentages of all dermoid cysts. These tumours may be totally asymptomatic and 15 percent of them are discovered incidentally on rectal and pelvic examination or on radiological evaluation. The treatment of rectal dermoid cyst is complete surgical removal. We present a case of dermoid cyst located at the submucosal layer of the posterior rectal wall. The patient presented in current paper was treated with complete submucosal cyst excision via transanal route and the mass was diagnosed as epidermoid type of dermoid cyst.
