The consultation

  • The treatment of a skin disorder may include a biopsy or cryotherapy.
  • The dermatologist may prescribe other tests and treatment or refer you to another medical specialist.
  • Plan approximately 15 minutes for the visit.

Information on procedures

Skin biopsy

A skin biopsy can be performed in three different ways, depending on the location and size of the skin lesion.

Punch biopsy

  • A local anesthetic is used to numb the area.
  • A hollow circular scalpel rotates over the skin area and lifts out a small piece of skin.
  • A little bleeding may occur. Pressure will be applied to stop any bleeding and the wound will be covered with a bandage.
  • Pain at the biopsy site is usually minimal. You can take over-the-counter pain reliever if needed.

Shave biopsy

  • A local anesthetic is used to numb the area.
  • A sharp blade is used to remove a thin piece from the top layer of skin.
  • A little bleeding may occur. Pressure will be applied to stop any bleeding and the wound will be covered with a bandage.


  • A local anesthetic is used to numb the area.
  • A scalpel is used to remove a skin lesion along with some of the healthy skin tissue around it.
  • The incision is closed with stitches and covered with a bandage.


Cryotherapy is a procedure that uses extreme cold (liquid nitrogen) to destroy tissue. It is often used to treat benign or precancerous skin lesions. It also helps save the area around the lesions and reduce the scarring as much as possible.

  • The dermatologist sprays liquid nitrogen on the area being treated to freeze it.
  • The freezing may cause some discomfort and the treated area will become red soon after your procedure. It may also blister and swell. If this happens, don’t break open the blister.
  • You may also see clear drainage on the treated area. This is normal.
  • The treated area will heal in about 7 to 10 days.

Test results and follow-up

  • The dermatologist will discuss test results or treatment options with you and send a written report to the referring physician within 10 working days.
  • Results will also be available in your electronic medical record. For information on the creation of an account and how to access your electronic medical record, visit MyChart.
  • If a follow-up appointment or an appointment with another medical specialist is required, we will call you to book an appointment.
