Keratin Cyst Picture

Keratin 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. They are smooth to the touch, vary in size, and are generally round in shape.
