1. What should I do before Skin Biopsy?

Before the skin biopsy, tell your doctor if you:

  • Have been diagnosed with a bleeding disorder
  • Have experienced excessive bleeding after other medical procedures
  • Are taking blood-thinning medications, such as aspirin, aspirin-containing medications, warfarin (Coumadin) or heparin
  • Have a history of skin infections, including impetigo
  • Are taking medications that suppress the immune system, such as diabetes medications or medications used after an organ transplant

2. What should I do after Skin Biopsy?

Try not to bump the biopsy site area or do activities that might stretch the skin. Stretching the skin could cause the wound to bleed or enlarge the scar.

How to care for the biopsy site while it heals:

  • Wash your hands with soap and water before touching the biopsy site.
  • Wash the biopsy site with soap and water. If the biopsy site is on your scalp, use shampoo.
  • Rinse the site well.
  • Pat the site dry with a clean towel.
  • Cover the site with an adhesive bandage that allows the skin to ventilate.

Continue caring for the biopsy site until the stitches are removed. For shave biopsies that don’t require stitches, continue wound care until the skin is healed.

1. How long does Skin Biopsy last?

A skin biopsy typically takes about 15 minutes total, including the preparation time, dressing the wound and instructions for at-home care.

2. How is the procedure of Skin Biopsy?

Depending on the location of the skin biopsy, you may be asked to undress and change into a clean gown. A doctor or nurse then cleans the area of the skin to be biopsied. Your skin may be marked with a surgical marker or marking pen to outline the biopsy area.

You then receive a local anesthetic to numb the biopsy site. This is usually given by injection with a thin needle. The numbing medication can cause a burning sensation in the skin for a few seconds. Afterward, the biopsy site is numb and you shouldn’t feel any pain or discomfort during the skin biopsy.

What you can expect during your procedure depends on the type of biopsy you’ll undergo.

•   For a shave biopsy, your doctor uses a sharp tool, double-edged razor or scalpel to cut the tissue. The depth of the incision varies depending on the type of biopsy and the part of the body being biopsied. A shave biopsy causes bleeding. Bleeding is stopped by applying pressure to the area or by a combination of pressure and a topical medication applied to the biopsy site.

•   For a punch biopsy or an excisional biopsy, the procedure involves cutting into the top layer of fat beneath the skin, so stitches may be needed to close the wound. A dressing or adhesive bandage is then placed over the site to protect the wound and prevent bleeding.

3. What happens after the procedure?

If you had stitches after the procedure, keep the area as clean and as dry as possible. Your doctor will tell you when the stitches should be removed (usually within one week). If adhesive steri-strips (which look like small pieces of tape) were used to close the incision, do not remove them. They will gradually fall off on their own. If the strips do not fall off on their own, your health care provider will remove them at your follow-up appointment.

The tissue is processed, and a pathologist examines the skin biopsy sample under a microscope to determine if there is any disease. The results usually come back within one to two weeks.
