A sebaceous cyst is a closed sac or cyst below the surface of the skin that fills with a fatty white, semi-solid material called sebum. Blocked sebaceous glands, swollen hair follicles, or trauma to the skin can cause such cysts. Sebaceous cysts are not cancerous, though if left untreated they may grow until they become unsightly, painful, infected, or all of the above. Surgical excision of a sebaceous cyst is a simple procedure to completely remove the sac and its contents. An infected cyst may require oral antibiotics or other treatment before excision.
