title: [Case of presacral dermoid cyst].
abstract: A case report of a presacral dermoid cyst in an adult. A 39-year-old man visited our hospital because of lower abdominal pain. A soft mass was palpable on the right side wall of rectum. Computed tomographic (CT) scan, transrectal ultrasonography and MR imaging showed presacral cystic tumor with a diameter of 10 cm. The tumor was resected by using a sacral approach. It contained muddy substance and hairs. Histopathological examination showed that the tumor wall was made of stratified squamous epithelium with skin appendage. Hence, it was diagnosed as a dermoid cyst. After operation, wound infection and dehiscence occurred, but it healed after conservative treatment. Complete excision of developmental cysts is advised because of possibility of malignancy and infection.
