Scalp Cyst
A scalp cyst is s sebaceous cyst (also called epidermal cyst, keratin cyst, or
epidermoid cyst) is a closed sac or cyst below the surface of the skin that fills with a
fatty white, semi-solid material called sebum. Blocked sebaceous glands, swollen hair
follicles, or trauma to the skin can cause such cysts. The scalp, ears, genitals, and face
are common sites for sebaceous cysts, though they may occur anywhere on the body except
the palms of the hands and soles of the feet |
