Cysts are non-cancerous, closed pockets of tissue that can be filled with fluid, pus, or other material. They occur when a region of the skin invaginates. Cysts are common on the skin and can appear anywhere. When they occur on the body, they care called epidermoid cysts. In the scalp, they are called pilar cysts. Cysts may become infected and require antibiotic therapy. These benign growths often do not require treatment, but they can be easily removed with a small, in office procedure.
Milia are tiny epidermoid cysts. They appear as tiny, yellowish bumps on the face. Milia are mostly of an aesthetic concern for patients. They may be removed in the setting of a medical facial with extraction by your dermatologist.
