Abstract
Sacral region epidermis cyst in an adult is a comparatively rare disease.
We report 3 cases in which we adapted our approach to the tumor size and removed the tumor surgically by transendothelial sacrum and intraperitoneal speculum assistance.
Case 1 : A 49-year-old woman had perianal pain and was diagnosed. We performed extirpation using the transsacral approach for a cystic tumor of diameter 5cm in the rectum outside of the right rear buttocks. Case 2 : We made a checkup in gynecology for abdominal pain in a 25-year-old woman and found retroperitoneal tumor with oophoron internal bleeding. We performed transperitoneal (laparoscopic assist) tumorectomy for a mass of 9cm in diameter. Case 3 : A 53-year-old woman with an oppressive feeling in the buttocks underwent extirpation by the transsacral approach upon diagnosis of a presacral cystic tumor of median left side of the buttocks. The tumors of three cases have a film, and are diagnosed as epidermoid cyst histopathologically without invasion to the surrounding organs. This disease is an embryonally persistent benign tumor, but extirpation (complete excision) of low invasiveness is necessary, because there are reports on the malignant degeneration, the rate of infection is high, and recurrences are observed.
