Localization of primitive neoplasms the retrorectal or presacral space is rare in adults as most of these tumors are congenital. Developmental cysts are included within the group of retrorectal congenital cystic neoplasms and are slowly-progressive cystic neoplasms. Because of their localization, their manifestation is delayed, despite their congenital nature. Their form of presentation is varied and is caused by compression of the surrounding organs or infectious complications of the cyst. In the present case, we have 55 yr old female with complain of low back painand pus dyscharge from perineal region. Further examination reveal 84*54*49mm lesion in posterior perianal region on either side of natal cleft with cutaneous opening within natal cleft. Post operative biopsy suggestive of epidermoid cyst.
