Overview

A skin cyst is a lump just under the skin. These cysts can form when a hair follicle becomes blocked. They are common in acne and may occur on the face, neck, back, and genitals. But they can form anywhere on the body. These cysts aren't cancer, and they don't lead to cancer. They tend not to hurt, but they can sometimes become swollen and painful. They also may break open (rupture) and cause scarring.

These cysts may not cause problems. They may not need treatment. If a cyst is swollen and hurts, the doctor may inject it with a medicine or treat it with antibiotics if it's infected. But sometimes a painful or infected cyst will need to be removed or opened. In those cases, the doctor will use numbing medicine and then will cut into the cyst to drain it or remove it.

How can you care for your child at home?

• Don't squeeze the skin cyst or poke it with a needle to open it. This can cause swelling, redness, and infection.
• Keep the area clean with soap and water.

After a cyst is removed

• If your doctor told you how to care for your child's wound, follow your doctor's instructions. If you did not get instructions, follow this general advice for wounds without stitches:
  • Keep the wound bandaged and dry for the first day.
  • After the first day, wash around the wound with clean water 2 times a day. Don't use hydrogen peroxide or alcohol, which can slow healing.
• If your child has stitches, you may get other instructions. You will have to come back to have the stitches removed.
