Punch Biopsy


Transcript

Doctors usually perform a punch biopsy for deeper skin lesions.

Your doctor will rotate a circular, hollow blade around the lesion until it cuts completely through the epidermis and dermis.

He or she will remove a small cylinder of skin, usually smaller than the size of a pencil eraser, containing all layers of the skin and lesion.

Depending on the size of the sample, the area may or may not be closed with stitches.
