Text
|
This technique is typically used by dermatologists to sample skin rashes and small masses. After a local anesthetic is injected, a biopsy punch, which is basically a small size cutter (3 or 4 mm in diameter), is used to cut out a cylindrical piece of skin. The hole is closed with a suture and heals with minimal scarring. |
