Post Operative Instructions – Biopsy

Leave bandage in place for 1-12 hours.  You may continue your normal bathing routine (bath, shower) – gently cleansing the affected areas with soap and water.  You may also go swimming in pool or ocean (no lake) unless otherwise instructed.

If needed:

  1. Cleanse the area with Hydrogen peroxide 1-2 times a day.  Use alcohol in the scalp to avoid bleaching dark hair.
  2. Apply a thin layer of antibiotic ointment (Polysporin, Aquaphor, Vaseline ointment).
  3. Cover with a breathable band-aid if indicated.  Rotate the direction of the band-aid daily.  If a band-aid is used during the day, you may want to leave area open at night.

The area may develop a small red ring and a soft central crust that may be yellow-green.  Do not let the area become too dry and form a thick scab or stay too moist.

If bleeding occurs, press the area continuously with a clean gauze or bandage for 10 minutes.  Don’t look!! – Then check the area.  If bleeding persists, repeat for 10 minutes.  If bleeding continues, call the office.

Remember:  Surgery means that part of the skin is traumatized.  A scar is inevitable.  We, of course, attempt to have this scar be as inconspicuous as possible.

If a specimen was sent to the pathologist for examination, you should receive a letter or phone call with the lab results by the end of 3 weeks.  If you have not heard from the office in 2 weeks, then please call.

Post Operative Instructions – Cryosurgery (Liquid Nitrogen Freezing)

Liquid nitrogen is a cold, liquefied gas with a temperature of 196 degrees below custome writing zero Celsius (minus 321 degrees Fahrenheit).  It is used to freeze and destroy superficial skin growths such as warts and seborrheic keratoses.  It can also be used to treat premalignant skin lesions known as actinic keratoses.

Liquid nitrogen causes stinging and mild pain while the growth is being frozen and then thaws.  The discomfort usually lasts less than fifteen minutes.  On the fingers, a throbbing pain will occasionally last a few hours.

After freezing, your skin will become swollen and red, and it may blister during the first 24 hours.  A scab will form and will typically fall off by itself in one to three weeks.  The skin will usually be red first and then return to its normal color.  The area may remain lighter than the surrounding skin, but that is usually a temporary change.


  1. The treated area may develop a blister during the first 24 hours.
  2. Clean the area daily with soap and water.  If the area is oozing, use peroxide or alcohol until the oozing ends.  If a blister occurs, the blister may be pierced with a sterile lancet.
  3. The initial discomfort will improve during the following day.
  4. If the blister roof is accidentally removed, apply Polysporin ointment or Aquaphor to the blister base twice daily and cover with a breathable bandage.  AVOID NEOSPORIN AS IT CAN CAUSE A RASH IN SOME PEOPLE.  Rotate the direction of the bandaid to minimize irritation.  The area can be left open at night.
  5. Contact the office if there is any evidence of infection or increasing pain.

REMEMBER:  Cryosurgery means that part of the skin has been traumatized.  Although we attempt to minimize damage, a residual mark may occur.
