Management of Perineal Epidermoid Cyst in a 20-year-old Female

Abstract

Epidermoid cysts are cutaneous or subcutaneous masses caused by the implantation of epidermal elements into the dermis. This case report presented an epidermal cyst of the perineum clinically mimicking endometriosis in a female patient. A 20-year-old virgo female patient was admitted to our clinic with complaints of severe pain, especially in the right leg, and postmenstrual bleeding for three years. In the transrectal ultrasound, a 54*39 mm cystic lesion with dense internal echo was detected in the medial neighborhood of the pelvic floor right obturator internus muscle. Since the cystic lesion detected in the contrast-enhanced pelvic MRI was evaluated as an epidermoid cyst and no significant endometrioma or endometriosis focus was detected, an operation was planned. Surgical excision should be performed not only for symptom relief and diagnosis but also to exclude rare malignancy. However, it is vital to master the pelvic and perineal anatomy along with careful surgery.
