A distinction is made between so-called epidermoid cysts and trichilemmal cysts. They hardly differ in their appearance. Epidermoid cysts are more likely to be found on the back or face, whereas trichilemmal cysts are mostly located on the scalp. The difference between epidermoid cysts and trichilemmal cysts is that the former have an outlet duct that is connected to the surface of the skin. This can look like a small yellow dot. Trichilemmal cysts, on the other hand, are located under the top layer of skin and have no open connection to the outside world.

Most sebum cysts develop for no apparent cause.
Young adults in particular are affected. They are often associated with acne, which is more common. In this case, one also speaks of secondary sebum cysts, as they arise as part of an underlying disease, namely acne. So-called primary sebum gland cysts that develop on healthy skin without a previous illness usually have no tangible cause. They arise from blocked ducts of the sebum glands. However, why this happens to one and not to the other is not clear. In very rare cases, sebum gland cysts occur with hereditary genetic defects. Then, however, a large number of sebum cysts can be found. Such genetic defects have been described for the occurrence of trichilemmal cysts, which are mainly found on the scalp.

The question of the medication taken is also important for the diagnosis. Taking the drug ciclospoprin A, for example, can lead to an increased incidence of sebum cysts.
As a rule, sebum cysts do not cause symptoms. They are usually symptom-free and only represent a cosmetic problem for those affected.
Sebaceous cysts rarely cause symptoms such as pain, increased swelling, and redness. That is the case when they are inflamed.

Trichilemmal cysts of the scalp can sometimes become very large, so that those affected find them extremely annoying. Malignant tumors can develop from sebum gland cysts only in very rare cases.
