Introduction to Shave Biopsy

A shave biopsy, or shave removal, is performed for various types of skin growths that may not be suitable for treatments like cryotherapy. It's commonly used for lesions concerning skin cancer, benign moles, or other growths. The skin is numbed with local lidocaine, and a small razor blade tool is used to scrape off the lesion, leaving it flush with the skin. The wound resembles a small scrape mark, and no stitches are required.

After the Procedure

  • Immediately After: A pressure bandage is applied to the area. Keep it dry and covered for 24 hours, avoiding showers until the next day.

  • Daily Care: After the first 24 hours, remove the bandage, wash the area with soap and water, and apply Vaseline or Aquaphor. Cover with a bandage or nonstick dressing like a Telfa Pad, using Hypafix tape, if available. Repeat daily until the wound heals.

  • Biopsy Results: Expect a call with your biopsy results after 2 weeks.

Complications and Solutions

  • Infection: If you notice excessive redness, pain, oozing pus, or fever greater than 100.4°F, contact your doctor, as it may be an infection.

  • Bleeding: If bleeding occurs, hold pressure for 20 minutes. Over-the-counter coagulants like BleedStop may help, especially if you are on blood thinners. If bleeding continues, call your doctor.

Scar and Possible Regrowth

Typically, a shave biopsy leaves a flat pink circular scar, or sometimes a small divot-like scar, similar to an acne or chickenpox scar. Consider this potential scarring if removing a spot for cosmetic reasons, as the scar may be more noticeable than the growth. There's also a slight chance the spot could grow back.
