Skin Biopsy Procedure
A skin biopsy is a quick and easy outpatient diagnostic procedure that usually takes only 10 to 15 minutes to complete. Your dermatologist will explain to you why the procedure is needed, how it is done, and the risks involved, and ask for your consent to undergo it.
Before a skin biopsy
Your dermatologist will clean the area being biopsied with a disinfectant. A local anesthetic will then be injected into the area to make it numb.
During a skin biopsy
Once your skin has become numb, your dermatologist will remove a small sample of skin affected by using a puncher, razor, or scalpel. A few stitches might be needed afterward.
After a skin biopsy
The area will be covered with bandages and instructions will be given to you on how to take care of the wound.
