Epidermal cyst of the preauricular region represents an unusual clinical lesion. It is intradermal or subcutaneous sac-like structure that is surrounded by keratinized stratified squamous epithelium. We report a case in which a 49-year-old man developed an epidermal cyst presenting as a large preauricular swelling causing pain and tenderness. The lesion was surgically excised, microscopic examination revealed the epidermal cyst. Therefore we report the case along with review of literature. (J Clinical Otolaryngol 2007;18:241–244)
