A skin biopsy is a skin exam in which a sample of skin tissue is removed, processed, and examined under a microscope.   It is necessary in diagnosing diseases of the skin, such as skin cancer, psoriasis, or bacterial and fungal infection. 

There are three types of biopsies:

  • shave biopsy (removal of the epidermis, top layer of the skin)
  • punch biopsy (removal of a small section of the skin including deeper layer of the skin, dermis and superficial fat)
  • excisional biopsy (complete removal of the abnormal area of the skin)


Depending on the size, location, and type of lesion the dermatologist may decide which type of skin exam is required.
