Skin Cysts and Tumors
Skin cysts and tumors are skin problems that sometimes cause pain. Skin cysts are non-cancerous closed pockets or pouches of tissue that are filled with fluid or other material. They feel like small peas beneath the surface of the skin and usually feel smooth and roll under the skin when pressure is applied to them.
Skin tumors are abnormal growths of tissue that can be malignant (cancerous) or benign (harmless). Skin tumors become extremely common as people get older.
Some common benign tumors include:
- Warts (skin tumor resulting from a virus)
- Seborrheic keratoses (growths on the skin ranging from light skin color to dark brown)
- Nevi (skin growths such as moles or birthmarks)
What Causes Skin Cysts?
Cysts can develop as a result of infection, clogging of sebaceous glands, or around foreign bodies.
How Are Skin Cysts Treated?
Some cysts disappear on their own without treatment. Others require treatment that involves lancing (piercing with a sharp object) the cyst and draining it. Some cysts can be treated with an injection of cortisone medication. Cysts that do not respond to treatment can be removed through surgery.
What Causes Skin Tumors?
The cause of skin tumors is not known, but some people may be likely to develop more or less of them based on heredity.
How Are Skin Tumors Treated?
Often, no treatment is required for skin tumors. However, methods to treat skin tumors may include:
- Curettage and electrodesiccation: This involves scraping away the tumor tissues with a sharp surgical instrument called a curette. An electrosurgical unit may then be used to stop bleeding.
- Surgical excision: This involves cutting into the skin, removing the growth, and closing the wound with stitches.
- Cryosurgery: During this procedure, liquid nitrogen is sprayed directly onto the skin or an instrument is used to freeze the tissue.
