The Bottom Line

Elliptical excision is a routine, outpatient procedure where your dermatologist numbs your skin and cuts out a football-shaped piece of tissue containing the growth. The wound is then closed with stitches. The whole thing typically takes 15–45 minutes, and most people go home the same day and return to light activity within a day or two.

What Is Elliptical Excision?

An elliptical excision—sometimes called a fusiform excision—is the standard surgical method for removing a skin growth along with a small margin of healthy tissue around it. The cut is shaped like a narrow oval or football, which allows the wound edges to come together naturally and close in a smooth, straight line.

Dermatologists use this technique to remove moles (nevi), sebaceous cysts, lipomas, basal cell carcinomas, squamous cell carcinomas, and other skin lesions that need to be fully taken out rather than just biopsied. The elliptical shape is chosen because it produces far less puckering and scarring than a simple circular cut would.

Why Your Doctor Might Recommend This Procedure

Your dermatologist may suggest elliptical excision when:

  • A mole or growth looks abnormal or has changed
  • A biopsy has already confirmed skin cancer that needs wider removal
  • A cyst, lipoma, or benign growth is bothersome or keeps getting infected
  • A lesion is too large or deep to be treated by shave removal or freezing

Because the removed tissue is sent to a pathology lab, this method also gives your doctor a definitive answer about what the growth actually was—something that simpler treatments cannot always provide.

What Happens During the Procedure

The procedure takes place in your dermatologist’s office or a procedure room. Here is what you can expect step by step:

  1. Marking the site. Your doctor will examine the lesion and mark the planned cut lines on your skin, orienting the ellipse along the natural tension lines of your skin (called Langer’s lines) to minimize scarring.
  2. Numbing the area. A local anesthetic—usually lidocaine with epinephrine—is injected around the site. You may feel a brief stinging or burning sensation for 15–30 seconds. After that you should feel only pressure, not pain. The epinephrine also helps reduce bleeding.
  3. Removing the tissue. The surgeon makes two converging incisions to create the elliptical shape, cutting down through the full thickness of the skin. The tissue is lifted out carefully and sent to a pathology lab.
  4. Controlling bleeding. Any small blood vessels are cauterized or tied off. The wound will look much worse at this stage than it will after closure—don’t be alarmed.
  5. Closing the wound. Most excision sites are closed in two layers: absorbable stitches placed beneath the skin to reduce tension, and non-absorbable stitches (or sometimes surgical staples or skin glue) on the surface. Layered closure is the key to a flat, narrow scar.
  6. Dressing the wound. A sterile bandage is applied. You’ll receive written instructions on wound care before you leave.

Recovery and Wound Care

Most people feel mild soreness for a day or two that is easily managed with over-the-counter pain relievers like acetaminophen. Here is what the typical recovery looks like:

  • Day 1–2: Keep the site clean and dry. Some oozing of clear or slightly blood-tinged fluid is normal.
  • Days 2–7: Clean the wound once or twice daily with gentle soap and water or saline, apply a thin layer of petroleum jelly (Vaseline), and cover with a non-stick bandage. Keeping the wound moist—not wet—speeds healing and reduces scarring.
  • Suture removal: Surface stitches are typically removed at 5–7 days for face/neck wounds and 10–14 days for the body or scalp. Absorbable deep stitches dissolve on their own over several weeks.
  • Scar maturation: Scars continue to soften and fade for 12–18 months. Early scars may look pink, raised, or firm—this is normal. Applying SPF 30+ sunscreen to the scar once it is healed helps prevent permanent darkening.

Activity restrictions: Avoid heavy lifting, vigorous exercise, or anything that strains the wound for 1–2 weeks, especially for wounds on the trunk. Physical activity increases blood pressure and tension on the wound, which can cause bleeding or the wound to open.

When to See a Dermatologist

  • You have a mole, growth, or skin spot that has changed in size, shape, or color
  • A skin growth is bleeding, crusting, or not healing after several weeks
  • You have a known skin cancer diagnosis that needs surgical removal
  • A cyst or lump is painful, infected, or growing
  • Your wound after excision shows signs of infection: increasing redness, swelling, warmth, pus, or fever

Frequently Asked Questions

Will it hurt?

The numbing injection causes brief stinging, but the procedure itself should be pain-free. Mild soreness after the anesthetic wears off is common and usually responds well to acetaminophen or ibuprofen. Tell your doctor right away if you feel anything sharp during the procedure—more local anesthetic can always be added.

How big will the scar be?

The incision is typically 3–4 times as long as the lesion is wide, because the elliptical shape requires tapered ends. For a 1 cm mole, you might have a 3–4 cm incision. Scars on the face tend to heal better than those on the chest or back. With good wound care and sun protection, most scars become barely visible over 1–2 years.

What if the margins are not clear?

If the pathology report shows cancer cells at or near the edge of the removed tissue, your doctor will discuss re-excision. This means removing a slightly wider margin of tissue around the original site to make sure all the cancer is gone.

Can I shower after the procedure?

Most surgeons advise keeping the wound dry for the first 24–48 hours. After that, a brief shower is usually fine—just pat the area dry gently and re-dress it right away. Avoid soaking in a tub, pool, or ocean until the wound is fully healed and all stitches are out.
