Post-Biopsy Instructions

  •  After 24 hours you may remove dressing and clean area with mild soap and water. 
  • Apply ointment 1-2 times daily: 
  • Aquaphor/Vaseline 
  • Continue to clean area 1-2 times daily with soap, water, and ointment then cover with a Band-Aid. The objective is to prevent a scab from forming. Repeat for one week. 
  • A rim of redness around the site is normal. Increasing redness, pus, heat, pain, and swelling at the site may indicate an infection and should prompt you to contact our office 

We should receive your results in one-two weeks. We will notify you of your results. If you have not heard from us 14 days after your procedure, please call us.

Care Instructions

There are literally hundreds of different kinds of lumps, bumps and cysts associated with the skin. Fortunately, the vast majority of these are harmless and painless. The chart below provides a guide for some of the most common forms of skin lumps, bumps and cysts.



  • Red, brown or purple growth; generally benign
  • Usually found on arms and legs
  • Feels like a hard lump
  • Can be itchy, tender to the touch and sometimes painful


  • Usually does not require treatment
  • Most common removal by surgical excision or cryotherapy (freezing it off with liquid nitrogen)

Epidermoid Cysts (Sebaceous Cysts)


  • Round small bumps, usually white or yellow
  • Forms from blocked oil glands in the skin
  • Most commonly appear on the face, back, neck, trunk and genitals
  • Usually benign; occasionally leads to basal or squamous cell skin cancers
  • If infected, will become red and tender
  • Can produce a thick yellow, cheese-like discharge when squeezed


  • Antibiotics might be prescribed if there is an underlying infection
  • Dermatologist removes the discharge and the sac (capsule) that make up the walls of the cyst to prevent recurrence
  • Laser surgery may be used for sensitive areas of the skin, like the face



  • Red pimples around areas having hair
  • Inflammation of the hair follicles
  • Caused by infection or chemical or physical irritation (e.g., shaving, fabrics)
  • Higher incidence among people with diabetes, the obese or those with compromised immune systems


  • Topical antibiotics
  • Oral antibiotics
  • Antifungal medications
  • Eliminating the cause



  • Red, dome-shaped, thick bumps with craters in the center
  • Abnormal growth of hair cells
  • Triggered by minor skin injury such as a cut or bug bite
  • Ultraviolet radiation from sun exposure is the most common risk factor


  • Cryotherapy (freezing off the bump with liquid nitrogen
  • Curettage (surgically cutting out or scraping off)

Keratosis Pilaris


  • Small, rough white or red bumps that neither itch nor hurt
  • Usually worse during winter months or when there is low humidity and the skin gets dry


  • Usually does not require treatment
  • In most cases disappears on its own by age 30
  • Intensive moisturizing is the first line of treatment
  • For more difficult cases, use of medicated creams with urea or alpha-hydroxy acids



  • Soft fatty tissue tumors or nodules below the skin's surface
  • Usually slow growing and benign
  • Appear most commonly on the trunk, shoulders and neck
  • May be single or multiple
  • Usually painless unless putting pressure on a nerve


  • Usually does not require treatment unless it is compressing on the surrounding tissue
  • Easy to remove via excision



  • Soft fleshy growths under the skin
  • Slow growing and generally benign and painless
  • Pain may indicate a need for medical attention
  • May experience an electrical shock at the touch


  • Usually does not require treatment, particularly if it does not cause any symptoms
  • If it affects a nerve, it may be removed surgically

Skin Cysts


  • Closed pockets of tissue that can be filled with fluid or pus
  • Can appear anywhere on the skin
  • Smooth to the touch; feels like a pea underneath the surface
  • Slow growing and generally is painless and benign
  • Only needs attention if it becomes infected or inflamed


  • Usually does not require treatment; often disappears on its own
  • May need to be drained by a physician
  • Inflamed cysts respond to an injection of cortisone, which causes it to shrivel
