Epidermoid cysts contain keratin. Epidermoid cysts can occur sporadically, or as a part of a syndrome, such as Gardner?s syndrome.
The cyst begins as a nidus of epidermis below the epidermis. Keratin is produced, and with nowhere to be expelled, the cyst slowly enlarges. As the epidermis grows over the cyst, the epidermis typically stretches, allowing the white to yellow color of the cyst to be evident.
Cysts may become inflamed and resemble furuncles.
- The cyst is readily removed surgically.
- Aside from standard surgical excision, it can also be removed through a small incision with evacuation of the contents, followed by removal of the cyst wall through that small incision.
