In brief: Epidermoid Cyst

Epidermoid cysts, sometimes known as sebaceous cysts (a misnomer), contain a soft "cheesy" material composed of keratin, a protein component of skin, hair, and nails.
Epidermoid cysts form when the top layer of skin (epidermis) grows into the middle layer of the skin (dermis). This may occur due to injury or blocked hair follicles. The lesion may be asymptomatic unless rupture of the cyst occurs.
