Skin cysts, also known as sebaceous cysts, are slightly hardened, fluid-filled bumps within the skin. They can occur anywhere on the skin and often affect the face, neck, and torso. Instead, healthcare professionals call them epidermal cysts, keratin cysts, or epithelial cysts, according to American Family Physician.

Infections can occur if the cyst bursts.
