If you go to the dermatologist and he or she removes a mole, what do you think is done with that tissue sample?

Answer:

A doctor uses a circular tool to remove a small core of skin, including deeper layers (epidermis, dermis and superficial fat). Excisional biopsy. A doctor uses a small knife (scalpel) 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. The mole is removed in a procedure under local anaesthetic. You will be given a local anaesthetic by injection at the place on your body where the biopsy will be taken from. The local anaesthetic may sting a little when it is injected, however, the skin will then go numb and the operation should be pain-free.

Step-by-step explanation:

Surgical excision:

  • The dermatologist cuts out the entire mole and stitches the skin closed if necessary.

Surgical shave:

  • The dermatologist uses a surgical blade to remove the mole.
