Epidermal Inclusion Cysts
Medically reviewed by Drugs.com. Last updated on May 4, 2025.
Epidermal inclusion cysts are the most common skin cysts in adults. These cysts are usually round, firm lumps filled with a cheese-like material called keratin. They are also called epidermoid, keratin, or sebaceous cysts. They can be found almost anywhere on your body. The cysts are most common on the face, back, neck, chest, and around your ears. They can be caused by blocked hair follicle and oil gland ducts in your skin. The cysts can grow larger and make it hard for you to sit or walk if they are on your legs or back. Epidermal inclusion cysts may grow slowly but are not cancer.
