Skin lesion biopsy is the removal of a piece of skin to diagnose or rule out an illness which is often used for advanced stage skin cancer in Modern Cancer Hospital Guangzhou. This paper is going to present some types of skin lesion.
There are several ways to do a skin biopsy. Most procedures can be done in outpatient medical offices or your doctor's office,which procedure depends on the location, size, and type of lump or sore. You will receive some type of numbing medicine (anesthetic) before any type of skin biopsy.
Types of skin biopsies include:
· Shave biopsy
· Punch biopsy
· Excisional biopsy
· Incisional biopsy
The shave biopsy is the least invasive of all three techniques. Your doctor will remove the outermost layers of skin. You will not need stitches.
Punch biopsies are most often used for deeper skin spots or sores. Your doctor removes a small round piece of skin (usually the size of a pencil eraser) using a sharp, hollow instrument. If a large sample is taken, the area may be closed with stitches.
An excisional biopsy is done to remove the entire lesion. A numbing medicine is injected into the area. Then the entire lump, spot, or sore is removed, going as deep as needed to get the whole area. The area is closed with stitches. Pressure is applied to the area to stop any bleeding. If a large area is biopsied, a skin graft or flap of normal skin may be used to replace the skin that was removed.
An incisional biopsy takes a piece of a larger growth for examination. The area is injected with a numbing medicine. A piece of the growth is cut and sent to the lab for examination. You may have stitches, if needed. The rest of the growth can be treated after the diagnosis is made.
