A problem that I see frequently in my dermatology office is a cyst on the scalp. These are called pilar cysts, and they can be removed easily in the office under local anesthesia.
A pilar cyst appears as a movable nodule under the skin and is often found on the scalp. However, they can appear in other locations. They are derived from hair follicles and are encapsulated in a sac. The sac must be removed; otherwise, they will recur.
Removing Pilar Cysts
Patients often dislike pilar cysts either for cosmetic reasons or because they are uncomfortable. They can be removed as a simple outpatient procedure. In the video, the area is cleaned and numbed. A small incision is made over the surface of the cyst, and the contents including the sac are removed. A small, dissolving stitch is used to close the wound. The whole procedure took less than 5 minutes.
Pilar Cysts Dangerous?
Pilar cysts are not dangerous. However, they can be uncomfortable especially if they rupture and become inflamed. Most pilar cysts grow to be a certain size and stay there. Some can become quite large. The tendency to get them can run in families.
