There are several types of cysts on head: Dermoid Cyst. Dermoid cysts, known as pilar cysts, are congenital type of cysts that contain hair, fluid, teeth or sweat glands. Dermoid cysts can be located on or in the skin and usually occur on the face, lower back, inside the skull or in the ovaries.
Epidermoid cysts represent the most common cutaneous cysts. While they may occur anywhere on the body, they occur most frequently on the face, scalp, neck, and trunk. Historically, epidermoid cysts have been referred to by various terms, including follicular infundibular cysts, epidermal cysts, and epidermal inclusion cysts. The term epidermal inclusion cyst refers specifically to an epidermoid cyst that is the result of the implantation of epidermal elements in the dermis. Because most lesions originate from the follicular infundibulum, the more general term epidermoid cyst is favored.
