Sebaceous cysts vary in size from very small (< 1 cm or ½ inch) to very large (> 4-5 cm or 2 inches). They appear primarily on the face, back, lower neck or base of the ears, or anywhere else on the body.
They may be associated with a “blackhead” which is a visible keratin-filled orifice communicating through the skin. Removal (excision) of the sebaceous cyst wall and the cyst content is the definitive treatment, most easily done when the cyst is not inflamed. When they become inflamed and infected like a “boil”, they require a more complex procedure and prolonged recovery. It is best to avoid this complication if at all possible. Therefore, if you have this condition, you should discuss this with your physician. These can get infected at the most inconvenient time in your life when you can least afford the time to deal with them.
