Biopsies
A dermatologist performs skin biopsies to diagnose or rule out skin conditions and/or diseases. Biopsies can be used to remove skin lesions as well. After the skin is examined and numbed, your dermatologist will use a special tool to remove a skin sample from your body and submit this for evaluation by a dermatopathologist. A dermatopathologist is an expert physician who has undergone specific and additional education to diagnose skin conditions with microscopic analysis. Skin biopsies help your board-certified dermatologist diagnose and better treat your skin condition. Not all skin conditions :
There are three main types of skin biopsies:
Shave biopsy: The dermatologist uses a blade to retrieve a small horizontally oriented section of skin (epidermis and portion of the dermis).
Punch biopsy: The dermatologist uses a tool called a punch biopsy tool to retrieve a circular plug of skin from an area of question. This type of biopsy may require one or a few stitches.
Excisional biopsy: The dermatologist uses a small scalpel to remove a larger lesion (or portion of lesion), usually in an ellipse shape. This type of biopsy is usually close with stitches.
