Skin biopsy

What is a skin biopsy?

A skin biopsy is a short procedure where a sample of skin is removed and sent to the Pathology laboratory to be analysed under the microscope. A skin biopsy will help to diagnose your skin condition and plan treatment. The procedure is usually done under local anaesthetic. This means that you will be awake and a small injection will be used to the numb the skin from which the biopsy is needed.

A small round bladed instrument is used to remove a round core of tissue ranging from 3 to 4 millimetres in diameter. 1 or 2 stitches are often used. A small scar which looks like a fine 4mm line will result.

A small eye shaped piece of skin is removed. Stitches are used to close the area and a small linear scar results. The scar may be 1 to 5 cm in length depending on the size of the biopsy that is required.

The surface of a lesion is shaved off. The roots of the lesion, if there are any, are not removed. A scab will form which will take a week to separate. Stitches are not required. You will have a pale, flat scar that is usually the same outline as the base of the lesion. With time this will be minimally perceptible.

Preparing for a skin biopsy

To prepare for the procedure you should follow the steps below:

  • Prepare a list of medications that you are taking. Ensure you have you have notified your Dermatologist if you are on any blood thinning medications such as aspirin or warfarin, in case these need to be stopped.
  • Make sure you have a supply of your usual painkiller such as paracetamol.
  • Eat and drink normally. Light meals are preferable on the day of the procedure.
