Epidermoid cysts represent the most common cutaneous cysts. While they may occur anywhere on the body, they occur most frequently on the face, scalp, neck, and trunk. Such cysts occur when surface skin elements are underneath the top layer of skin.
Depending on size and location, most often the cyst can be removed in an in-office procedure. The cyst removal procedure involves injecting the site with a numbing medication, waiting for it to reach anesthetic effect, and then excising the lesion. The site is then sutured closed, if necessary.
