What is a dermoid cyst?

A dermoid cyst is a growth of normal tissue enclosed in a pocket of cells called a sac. This tissue grows in or under your skin in an unexpected location.

Dermoid refers to something that’s like skin. A cyst is a lump or bump that may contain fluid or other material. Most often, dermoid cysts contain a greasy yellow material, but they may contain:

• Bone.
• Fluid.
• Hair.
• Nerves.
• Skin.
• Sweat glands.
• Teeth.

Dermoid cysts can be anywhere on your body. The ones close to your skin surface may look like small lumps. People can also develop dermoid cysts deeper inside your body.

At first, a dermoid cyst can seem like a tumor, but these cysts usually aren’t harmful. You or your child may need surgery to remove a dermoid cyst. It won’t go away on its own.
