[Cystic sacrococcygeal lesions].

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.
