Epidermoid cyst at a rare location, as a content of inguinal hernia: A case report with a review of the literature

Epidermoid cysts can occur in a variety of locations including the face, trunk, neck, extremities, and scalp. No case of epidermoid cyst as content of inguinal hernia has been reported so far; however, cases with dermoid, teratoma, lipoma, lymphangioma and leiomyoma as content of inguinal canal have been reported. A 29-year-old female presented with a lump in the left inguinal region that was clinically diagnosed as left inguinal hernia. The patient was planned for laparoscopic inguinal hernia repair after routine investigation. Intraoperatively, a cystic mass was found to be attached to the left round ligament that was excised completely. Histopathological report was consistent with epidermal inclusion cyst. Inguinal epidermoid cyst mimicking inguinal hernia is a rare entity. If such a cyst is encountered during operation, it should be completely excised.
