Thickness biopsy

John L. Bezzant,M.D.

One of the typical lesions is anesthetized, and then a 4 mm diameter punch of the full thickness skin is done. The skin in most areas is 2 mm in depth, and 4 mm on the back. The wound is then closed with 4-0 monofilament suture using a vertical mattress closure, and one or two sutures are placed.
