Epidermoid Cysts
Epidermoid cysts, also called epidermal inclusion cysts, are common in the eyelids. They may arise spontaneously or as a result of the entrapment of epidermis beneath the skin surface following surgery or trauma. Epidermoid cysts are lined with keratinized stratified squamous epithelium and contain keratin (Fig 13-10).
