A skin biopsy is a procedure in which a sample of skin tissue is removed, processed, and examined under a microscope.
✽ A skin biopsy is usually undertaken using a local anaesthetic injection into the skin to numb the area.
✽ After the procedure, a suture or dressing may be applied to the site of the biopsy.
✽ Several different methods may be used to obtain a skin sample, depending on the size and location of the abnormal area of skin.
✽ The skin sample is placed in a solution, such as formaldehyde, or in a sterile container if infection is suspected. In each of these procedures, the tissue is processed and then examined under a microscope.
✽ A skin biopsy removes cells or skin samples from the surface of your body.
✽ The sample taken from a skin biopsy is examined to provide information about your medical condition.
✽ A dermatologist uses a skin biopsy to diagnose or rule out certain skin conditions and diseases.
