Dermal Cyst Excision


A dermal cyst excision is a procedure to remove a cyst that has grown under your skin.


Before your procedure:

  • Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.
  • An IV is a small tube placed in your vein that is used to give you medicine or liquids.
  • Local anesthesia is a shot of medicine put into the skin near your cyst. It is used to numb the area and dull the pain. You may still feel pressure or pushing during the procedure.

During your procedure:

An incision will be made on or around your cyst. Your healthcare provider will use his fingers to push the fluid out of the cyst. He will then use a tool to remove the rest of the cyst sac. If your cyst is infected, he may drain it first and then remove it completely another time. The incision may be closed with stitches or left open to heal. A bandage will be placed over your incision to keep it clean and dry, and to prevent infection.

After your procedure:

You will be taken to a room to rest until you are fully awake. Healthcare providers will monitor you closely for any problems. Do not get out of bed until your healthcare provider says it is okay. When your healthcare provider sees that you are okay, you will be able to go home or be taken to your hospital room.

  • Pain medicine may be given to decrease pain. Do not wait until the pain is severe before you ask for more medicine.
  • Antibiotics help prevent infection caused by bacteria.
  • Steroids help decrease inflammation around your incision.


  • You may bleed more than expected or get an infection. A scar may develop as the incision heals. The scar may become large and raised. Your stitches may come apart. Blood may build up in your wound and cause a large, swollen bruise. The nerves near your incision may be damaged.
  • Without treatment, your cyst may grow larger. It may burst open. The cyst may become infected and painful. The cyst may interfere with your daily activities.
