WHAT IS A SKIN BIOPSY?
A skin biopsy is a method to diagnose skin diseases. It involves removing a small sample of skin from the disease area and examining under microscope. The sample is usually sent to a laboratory for examining under microscope.
WHAT ARE THE TYPES OF SKIN BIOPSY?
Skin biopsy is done under local anesthetic injection, given only at the site of the biopsy
Three main types of skin biopsies are:
- Shave biopsy A tool similar to a razor to shave a small section of the top layers of skin.
- Punch biopsy A doctor uses a circular tool to remove a small section of skin including deeper layers
- Excisional biopsy A small knife (scalpel) is used to remove an entire lump or an area of abnormal skin, including a portion of normal skin down to or through the fatty layer of skin.
