What Is a Pilar Cyst on the Scalp?

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. A pilar cyst, also known as a trichilemmal cyst, is a common benign growth that typically occurs on the scalp. These cysts are derived from the outer root sheath of hair follicles and are filled with keratin, a protein that makes up hair and nails. Pilar cysts are generally harmless but can cause discomfort or cosmetic concerns for some individuals.

Characteristics of Pilar Cysts

Pilar cysts are usually firm, round, and mobile under the skin. They can vary in size, often ranging from a few millimeters to several centimeters in diameter. Unlike epidermoid cysts, which are more common on the face, neck, and trunk, pilar cysts predominantly occur on the scalp.

Causes and Risk Factors

The exact cause of pilar cysts is not well understood, but they are believed to be related to genetic factors. They often run in families, suggesting a hereditary component. Pilar cysts are more common in middle-aged adults and are seen more frequently in women than in men.

Symptoms

Most pilar cysts are asymptomatic, meaning they do not cause any symptoms. However, they can become painful if they become infected or inflamed. In some cases, the cysts may rupture, releasing their keratinous contents, which can lead to irritation and secondary infection.

Diagnosis

Diagnosis of a pilar cyst is typically made through a physical examination. A healthcare provider can often identify the cyst based on its appearance and location. In some cases, imaging studies or a biopsy may be performed to rule out other conditions.

Treatment

Treatment for pilar cysts is not always necessary, especially if they are not causing any symptoms. However, if the cyst becomes painful, infected, or cosmetically bothersome, surgical removal may be recommended. The procedure is usually straightforward and can be performed under local anesthesia.

Conclusion

Pilar cysts are benign growths that commonly occur on the scalp. While they are generally harmless, they can cause discomfort or cosmetic issues for some individuals. Treatment is available for those who experience symptoms or wish to have the cysts removed for cosmetic reasons. Understanding the nature of pilar cysts can help individuals make informed decisions about their health and treatment options.
