It’s not often that an experienced dermatologist is surprised by a cyst but the good doctor wasn’t expecting the vast amount of pus that came out of this epidermoid cyst. That’s because instead of manifesting itself as a large lump visible from the outside and was deep. Very deep. So much was coming out that Dr Gilmore had slow motion replays of the steady stream coming out of his incision.
What are epidermoid cysts?
Epidermoid cysts usually don’t cause any pain and can often go untreated.
Treatment may be required if the cyst becomes red, swollen, painful, or is infected.
Squeezing out the contents of the cyst on your own can lead to infection.
Epidermoid cysts, also called sebaceous, keratin, or epithelial cysts, are small, hard lumps that develop under the skin. These cysts are common. They grow slowly. They do not cause other symptoms and are nearly never cancerous. Epidermoid cysts are often found on the face, head, neck, back, or genitals. They can range in size from 1/4 inch to 2 inches across. They look like a small bump, are tan to yellow in color, and are filled with thick, smelly matter. They do not cause any pain and can usually be ignored.
What causes epidermoid cysts?
Epidermoid cysts are usually caused by a buildup of keratin. Keratin is a protein that occurs naturally in skin cells. Cysts develop when the protein is trapped below the skin because of disruption to the skin or to a hair follicle. These cysts often develop in response to skin trauma, HPV infection, acne, or excessive exposure to the sun. An epidermoid cyst is more likely to develop in people with acne or other skin conditions.
