Abstract
Epidermal cysts are benign tumors derived from the epidermis or the epithelial hair follicle filled with keratin and lipid-rich debris, typically occurring in areas with a high-density of sebaceous glands. These cysts commonly occur on the face, scalp, neck and trunk, where the sebaceous glands are more active. Their localization within the bone is extremely uncommon. The current study details the case of a 24-year‑old male who presented with right otorrhea and ipsilateral hypoacusia having undergone right overlay myringoplasty for subtotal eardrum perforation. This patient represents a rare case of an epidermal cyst localized in the temporal bone (the fifth described in English-language literature), which may be considered as a complication of myringoplasty.
