Skin Biopsies
What is a skin biopsy?
A skin biopsy is a procedure in which a small sample of skin is removed for examination under a microscope. It helps diagnose skin conditions such as infections, inflammatory diseases, and skin cancer.
Types of skin biopsies
Shave Biopsy - A thin layer of skin is shaved off with a blade. Used for superficial skin lesions.
Punch Biopsy - A small, round section of skin is removed using a circular tool. Used for deeper skin conditions.
Excisional Biopsy - The entire lesion and some surrounding skin are removed with a scalpel. Used for larger or deeper growths.
What to expect during the procedure
- Preparation – The area is cleaned, and a local anesthetic is injected to numb the skin
- Biopsy – The provider removes the skin sample using the appropriate technique
- Closure – Bleeding is controlled, and the wound may be closed with stitches or covered with a bandage
- Duration – The procedure typically takes less than 15 minutes
