Giant Nevi Removal: Basics to Know


Congenital nevi (or nevus, if singular), refer to pigmented moles that some people are born with. They are formed when the pigment of the skin produces a great number of cells, called melanocytes. These nevi can be either small or large. A nevus can be classified as a giant one when it measures. Giant nevi are those measuring 3 inches across a new-born baby’s head or more than 8 inches in an adult’s body.

Giant nevi removal surgery is intended to remove the mole entirely or as much as is possible. In the procedure, doctors still need to make several cuts and stitches, or even give skin replacement to patients. It is possible to leave scars after the surgery.


A child can be a good candidate for giant nevi removal if:

  • Physically healthy and at a stable weight
  • The lesion on body is painful or itching or has developed other atypical features
  • The size and the location of the lesion is amenable to removal
  • Parents have a realistic and positive attitude toward the surgery and understand the surgeon’s treatment


To exactly calculate your costs, you need to know first that there are two kinds of mole removal: surgical and cosmetic removal.


This procedure would probably range from $800 to $1,500 depending upon the type of mole and the responsible plastic surgeon. Insurance usually covers it.


The cost of giant nevi removal for cosmetic reasons depends on the complexity of the mole and the removal difficulty. Typically, removing the first mole without insurance will need $130, and then $65 for the second and third.


To know about all the risks and complications associated with the procedure, you should have a talk with an experienced plastic surgeon.

You might undergo some of the following risks, including:

  • Bleeding
  • Infection
  • Poor healing of incisions
  • Hematoma
  • Anesthetic allergy
  • Fluid accumulation
  • Skin loss
  • Nerve damage
  • Skin discoloration and/or prolonged swelling
  • Unfavorable scarring


Firstly, before having a giant nevi removal, your plastic surgeon may recommend you:

  • Having lab or radiographic tests, or a special medical evaluation
  • Taking certain medications or adjusting current medications
  • Avoiding aspirin, anti-inflammatory drugs and herbal supplements as they can increase bleeding

Next, to prepare for a safe surgery, your plastic surgeon will usually do the following things:

  • Cleanse the treated area with alcohol, betadine, or another suitable material
  • Apply anesthetic, such as lidocaine to the treated area and wait for a while, to allow the blood flow to the area to diminish
  • Place a sterile drape over the treated area, if the surgical environment hasn’t been sterilized

Surgical steps

  • Your doctor will prescribe medications such as intravenous sedation and general anesthesia to ensure your comfort.
  • Your doctor will begin the excision around the edge of the visible lesion. Later on, the involved skin will be removed completely. If your doctor plans to have a serial of excision, the edges also need removal.
  • After the nevi has been removed, your doctor may use removable or absorbable sutures or staples to close your incisions. At the end, the incision will be covered with glue, tapes or bandages.


For better recovery, you are suggested to do these things:

  • Caring for sutures

If you are left with the basic thread-like sutures after surgery, you may be asked to keep the area moist with antibiotic ointment for about one week. However, some doctors may prefer to use liquid sutures to hold the skin in place like glue. In this case, these sutures will dissolve by themselves. And you don’t need to have special care for them.

  • Keeping the wound clean and dry

Other sutures without thread should stay dry and clean. You will be asked to put some antibiotic ointment at first, and then cover the wound with a bandage. When showering, you should be careful not to get the wound wet or soak it too long.

  • One to two weeks of minimal care

Keep the bandage for one or two weeks. Do not irritate the scab and let it fall off naturally. And just remember to follow the instructions above to prevent infection.
