Synopsis

Epidermoid cysts or epidermal inclusion cysts are also known as sebaceous cysts, which is a misnomer. These asymptomatic, semisolid cysts are filled with keratin. The cysts are lined by keratinizing epithelium that is responsible for the soft, "cheesy" keratin contents.

These cysts are common on the scrotum but are rarely found on the penis. The cysts can be located almost anywhere, and besides the scrotum, common places include the face, neck, scalp, or trunk.

The pathogenesis of genital epidermoid cysts is unknown. It is hypothesized that some epidermoid cysts may originate from median raphe cysts.
