Sebaceous Cysts - Causes & Treatments

Sebaceous cysts are small lumps that arise within the skin on the face, upper back and upper chest. A sebaceous cyst can form when the opening to a sebaceous gland becomes blocked. The oily substance called sebum continues to be produced but cannot escape to the outer skin surface.

Sebaceous Cysts

The cyst may remain small for years, or it may continue to get larger. These cysts are rare in children but common in adults. Sebaceous cysts are not cancerous.

Sebaceous cysts that occur in people with acne can be prevented by keeping acne under control with medication.

A sebaceous cyst usually does not need to be treated unless it is inflamed (red) or is causing a cosmetic problem. Inflamed cysts usually are treated by draining the fluid and removing the shell that make up the cyst wall. You also may be treated with antibiotics if the skin around the cyst is also inflamed. If a cyst is causing irritation or cosmetic difficulty, your physician can remove it by making a small incision in the skin and emptying the contents of the cyst and its wall.
