Sebaceous cysts are common skin cysts that can pop up really anywhere on the body but are more frequently seen on the head, back of the ears, neck, and trunk. In addition, some genetic disorders like Gardner's syndrome may predispose a person to develop sebaceous cysts. Some confusion arises around sebaceous cysts as these cysts contain keratin, and not sebum oil because they originate from the outer layer of the skin the epidermis and not the sebaceous glands.
In fact, the true name for sebaceous cyst is an epidermoid cyst, although many people, even healthcare professionals, still erroneously use the term sebaceous cyst. Given that the term sebaceous cyst is still often used in the medical community, this article will refer to the cyst as such.

Sebaceous cysts are painless, soft lumps or bumps that grow slowly just under your skin. They usually have a visible hole in the middle called a central punctum and can move freely when touched. You can see the keratin if the cyst becomes inflamed and breaks open. Keratin is a "pasty" or "cheesy" looking substance that may have a foul odor.
Some sebaceous cysts remain stable in size with time whereas others grow larger which may be uncomfortable and painful, especially if the cyst becomes inflamed. Sebaceous cysts, to the trained eye, are usually easily diagnosed by their appearance.
In some cases, a biopsy or skin culture may be necessary to rule out other conditions with a similar appearance. For instance, an abscess a collection of pus underneath the skin or a lipoma a noncancerous mass of fatty tissue can resemble a sebaceous cyst. To ensure a correct diagnosis, you should see your healthcare provider for a formal evaluation.
Sebaceous cysts most often disappear on their own and are not dangerous. As stated, however, they may become inflamed, tender, and even infected.

Inflamed cysts can often be treated by your healthcare provider who will inject a steroid into the cyst to calm and shrink it. But if your healthcare provider suspects the cyst is infected , it needs to be incised and drained to remove the infected material. If an infected sebaceous cyst is not promptly treated, the infection can spread into the surrounding skin.
This is called cellulitis , which is a more serious condition, often requiring an oral antibiotic in addition to incision and drainage. For complete surgical removal of the cyst, including the cyst wall, a healthcare provider will usually wait until the cyst is not inflamed or infected before excising it, as recurrence of the cyst is then much less common. Besides excision cutting out the cyst surgically , a study published in the Archives of Plastic Surgery reports on a CO2 laser treatment to remove sebaceous cysts with minimal scarring and low recurrence rates.
