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.
一例成人骶前皮样囊肿的病例报告。一名39岁男性因下腹部疼痛前来我院就诊。在直肠右侧壁可触及一个柔软肿物。计算机断层扫描（CT）、经直肠超声检查和磁共振成像（MR）显示一个直径为10厘米的骶前囊性肿瘤。采用骶骨入路切除该肿瘤。肿瘤内含有浑浊物质和毛发。组织病理学检查显示肿瘤壁由带有皮肤附属器的复层鳞状上皮构成。因此，诊断为皮样囊肿。术后发生了伤口感染和裂开，但经保守治疗后愈合。鉴于存在恶变和感染的可能性，建议对发育性囊肿进行完整切除。
