Eleven out of twelve cases of sacrococcygeal cystic lesions, 10 females and 2 males, with ages ranging from 12 to 64 underwent surgical excision with the pathological diagnosis of teratoma in 1, dermoid in 4 and epidermal cyst in 6. Most lesions were multicystic and located in the perirecto-coccygeal region, some are extending into the pelvic cavity. Occult lesions may bulge toward the rectal lumen and thus could be early detected by digital examination or proctoscopy. Early surgery is advocated for fear of malignant change and secondary infection and coccygectomy advised to ensure satisfactory exposure.
12例骶尾部囊性病变患者中，11例接受了手术切除，其中10例为女性，2例为男性，年龄在12岁至64岁之间。病理诊断为畸胎瘤1例、皮样囊肿4例、表皮样囊肿6例。大多数病变为多囊性，位于直肠周围-尾骨区域，有些延伸至盆腔。隐匿性病变可能向直肠腔内突出，因此可通过直肠指检或直肠镜检查早期发现。由于担心恶变和继发感染，主张早期手术，并建议行尾骨切除术以确保满意的暴露。
