Punch Biopsy of a Skin Lesion

Punch Biopsy of a Skin Lesion


A punch biopsy involves removing a small piece of skin using a circular blade called a punch.


The procedure is performed under a local anaesthetic and usually takes 10 to 15 minutes.

Your doctor will stretch your skin to make it easier to use the punch to remove a sample of tissue. The amount of tissue removed is usually less than 4 millimetres in diameter and about 1.5 millimetres deep.

They will either close the hole with stitches or use a dressing.
