Bowen’s Disease (Squamous Cell Carcinoma In Situ)

Serving Hamilton, Stoney Creek, Grimsby and surrounding areas

Bowen’s Disease:

  • Is usually a crusted, scaly, pink patch
  • May be as small as a 2 to 3 mm and as large as 20 cm or more across
  • Is usually present on sun exposed areas such as the ears, nose, face and tops of the hands
  • Is caused by the sun exposure that occurred 10 to 70 years before the spots appear
  • Is a low grade form of skin cancer caused by the sun
  • Spreads internally extremely rarely
  • Is a superficial form of squamous cell carcinoma, which affects only the uppermost layer of the skin

Prevention of bowen’s disease, and other skin cancers:

  • Wear a hat with a broad brim and protective clothing (e.g. long sleeves)
  • Avoid the outdoors when the sun is strongest between the hours of 10 am to 3 pm
  • Use a sunscreen year round with an SPF of at least 30
  • Wear a sunscreen which resists water and sweating and which protects against both UVA and UVB
  • Reapply sunscreen every hour if you are in water or sweating heavily
  • Wear sunscreen even if you are in the shade, it is still possible to burn
  • Avoid tanning beds
    • The ultraviolet light tanning beds produce is known to cause skin cancer

Treatment

Liquid Nitrogen:

  • Is a cold freezing spray that is applied in the office
  • It causes the spots to become red, swollen and crusted
  • The spots will heal within 7 to 14 days
  • You can bathe or shower normally
  • The treated areas do not need to be covered by bandages

Creams:

  • A variety of creams are available
  • Please talk to your doctor about your options

Levulan Photodynamic Therapy (ALA PDT):

What are the advantages of Levulan PDT compared with other treatments?:

  • Unlike creams it has the advantage of being able to treat large areas in a single visit
  • Unlike liquid nitrogen, the treatment is not painful
  • It treats precancerous spots before they can be seen
    • Preventing skin cancer from developing

Levulan-IPL Photodynamic Therapy:

  • Almost any area can be treated including:
    • Face and neck
    • Arms and hands
    • Feet and legs
    • Chest and back
    • Scalp
  • The Levulan-IPL PDT treatment works with most skin types (I-IV) (from pale Caucasian to dark European and very light Asian)
  • Levulan-IPL PDT cannot be used for darker skin types (V, VI) (South Asian, African) or if you have a tan
    • In this situation  I recommend Blue Light PDT instead, which:
      • Can be used in all skin types
      • Can be used even if the skin is tanned

  • As an added bonus, Levulan PDT also treats:
    • Brown freckling
    • Enlarged pores
    • Sun damage
    • Depleted skin collagen
  • All of these lead to smoother, younger looking skin and reduced redness at the same time
  • The cost of Levulan PDT is partially covered on most private drug insurance plans
  • The cost of Levulan PDT is not covered on the Ontario ODSP (OHIP) drug plan for patients over 65 years of age

Electrodessication and Curettage:

  • The skin around the bowen’s disease is injected with a local anesthetic to numb the area
  • The injection stings for a few seconds
    • After this, there is no pain or discomfort
  • The bowen’s disease is removed from the skin in a scraping motion with an instrument called a curette
  • As the area is numb from the anesthetic, this process is not painful
  • The curetted area is then treated with electrocautery, a hot electric needle
    • This is not painful as the area is still numb
  • Electrocautery stops and bleeding and kills any residual cancer cells
  • The lesion is scraped and cauterized a total of 3 times in one visit
  • No stitches are required
  • Antibiotic and a bandage are used to cover the wound
  • The day after surgery, the bandage should be removed and a small amount of antibiotic should be be applied
    • This should occur twice daily site is healed
  • Redness, pain, swelling or a discharge from the wound may be a sign of infection
    • The doctor should be informed immediately
  • You may bathe, shower and do your normal activities unless the bowen’s disease that has been removed is very large and there is a risk of the wound being damaged
    • The doctor will inform you about this
  • There is a small chance that the bowen’s disease could grow back

Surgical Excision:

  • The skin around the bowen’s disease is injected with a local anesthetic to numb the area
  • The injection stings for a few seconds
    • After this, there is no pain or discomfort
  • The bowen’s disease and a small amount of surrounding normal skin is cut with a scalpel and removed
  • As the area is numb from the anesthetic, this process is not painful
  • Stitches are used to close the opening
  • Antibiotic and a bandage are used to cover the wound
  • The day after surgery, the bandage should be removed and a small amount of antibiotic should be be applied
    • This should occur twice daily until the stitches are removed
  • Redness, pain, swelling or a discharge from the wound may be a sign of infection
    • The doctor should be informed immediately
  • The stitches are removed in 5 to 10 days
  • The removal of stitches is painless
