Do You Have Any Of These Spots?

Sunspots (actinic keratosis or solar keratosis)

  • These are due to chronic sun exposure: they are clearly visible areas of change in the skin, usually dry, irritable and scaly affecting a relatively large area
  • They are pre-cancerous and in Europe they are regarded as skin cancer
  • Treatment is usually necessary because of the potential for skin cancer. MolescreenPDT offers treatments of simple a CO2 peel to small areas or photodynamic therapy (PDT) for larger areas
  • We do not offer freezing with nitrogen because of scarring (click here to read more about Why Dr Johnson is so anti cryotherapy), the high likelihood of recurrence and the difficulty of treating large areas
  • Patient compliance is also an issue with various forms of self-administered topical treatments


Solar Keratoses

    • Dry scaly and sometimes sore patches mostly seen on face, ears, backs of hands and forearms. In extensivly damaged skin they are also seen on backs and legs. They are rare on covered areas such as genitals and buttocks
    • They are caused by long term sun exposure without sun protection
    • They are more common on outdoor workers and those who have played a lot of sport
    • Also present in most of the Queensland population after the age of 40 and sometimes earlier
    • Present in varying degrees depending on occupation
    • Pre-cancerous, mostly leading to Bowen’s Disease or SCC but may contribute to a form ofmelanoma in later life

Non-melanoma skin cancer

  • Easily seen and diagnosed especially with computerised dermoscopy which produces a very magnified image of the skin cancer viewed on a computer screen
  • Mostly caused by direct DNA damage by direct ultraviolet light
Bowen’s Disease

      • A non-invasive form of Squamous Cell Carcinoma (SCC)
      • After diagnosis with a biopsy it may be treated with shaving and cautery with careful monitoring for recurrence
      • Treated with photodynamic therapy (PDT) with the advantage of treating surrounding additional areas that may not yet be visible to the eye and non scarring
      • Cutting out is not usually required
Basal Cell Carcinoma

      • A common but usually non-fatal form of skin cancer
      • Does not usually metastasise (spread to involve other organs)
      • Unless it is adequately removed it is likely to recur
      • Should be treated definitely with surgery or if suitable with photodynamic therapy (PDT)
      • Indicates a strong risk of further skin cancer including melanoma and an additional risk factor for internal cancers.
Multifocal BCC

        • This is a fluorscopy image taken before Metvix activation showing the extent of the BCC being treated. There is a lot more BCC present than is visible to the naked eye
        • Usually 5mm to 10mm and irregular shaped, pink or red, flat and scaly, if present for some time may be much larger
        • Old multifocal BCCs may ulcerate
        • Caused by long term sun exposure without sun protection
        • Appears on exposed surfaces and areas poorly protected from the sun such as scalp, behind the ear and on the back
        • Very common
        • Usually non-fatal but may be disfiguring
        • Superficial and often present with associated satellites which may be difficult to see
        • If untreated máy become invasive oveer the long term
        • Removal may require skin grafts or flaps depending on size and location
        • If not removed properly will recur and lead to major problems
        • May be treated surgically or with Metvix PDT or Aldara. Metvix may a better option because it can treat a larger area and deal with unseen satellites
Solid/cystic BCC

        • Usually pink but may be pigmented and look like a mole. Raised. Often up to 10mm in size.
        • Caused by long term sun exposure without sun protection
        • Appears on exposed surfaces and areas poorly protected such as scalp, behind the ear and on the back
        • Very common
        • Usually non-fatal but may be disfiguring
        • May infiltrate the local area and is a problem particularly on scalps and faces
        • May be treated surgically or with Metvix PDT or Aldara (after shaving).
        • Infiltrating BCCs require extensive surgery and occasionally radiotherapy.
Squamous Cell Carcinoma

  • A less common but more dangerous form of skin cancer that may metastasise if not treated appropriately, correct diagnosis then becomes important
  • Nearly always requires surgical removal with adequate margins of normal skin

Keratoacanthoma

  • Fast growing wart-like skin tumour found on sun damaged skin
  • Usually found on lower legs and forearms but occasional on other areas
  • Best removed sooner rather than later
  • May outgrow its blood supply and fall off leaving a large unsightly scar
  • Small number are or become an invasive SCC
  • May respond to removal by shaving and cautery but if there is any evidence of invasive SCC they should be removed surgically with a wide excision
Invasive SCC

    • Often found in a background of solar keratosis in areas damaged by chronic sunlight exposure
    • Dry pink, red and scaly sometimes sore patches mostly seen on face, ears, backs of hands and forearms. In very damaged skin also on backs and legs
    • Potentially invasive and liable to spread to other body organs.
    • Should be removed surgically with an adeqauet margin

Melanoma

  • The most deadly common skin cancer which is found anywhere on the body.
  • Any new mole should be viewed with suspicion especially over the age of 45 years.
  • This always requires surgical removal with adequate margins of normal skin as indicated by subsequent pathology.

Lentigo maligna

  • Freckle-like melanoma found on skin with significant sun damage
  • Common on face and neck, hands and arms
  • Increasingly common

Superficial Spreading Melanoma

  • Most common melanoma
  • Generally looks like a mole
  • Found anywhere on the body, not just where there is exposure to the sun
  • Most commonly found on a back on a male and legs and forearms on women
  • Probably caused by sunburn before the age of 20 but other causes can include arsenic exposure and drugs used to treat cancer, arthritis or autoimmune conditions
  • Slightly more common on men
  • Most are found on over 50 year olds but may appear in teenagers
  • Children usually don’t get melanoma
  • Most melanomas appear in newer moles rather than moles present at birth
  • Most melanomas are slow growing over several years but some appear and grow over a short time
  • Melanomas change in appearance (evolve) and this may be demonstrated over several months
  • Changes that are seen may be changes in size, shape and/or colour – often a melanoma gets bigger, darker and more irregular in shape but sometimes it may get lighter and smaller. It is change that is significant
  • Thin melanomas have a better outlook, thicker ones are more dangerous. A thin melanoma will get thicker over time and potentially spread to involve other organs
  • Once a melanoma has spread there is no guaranteed cure

Nodular Melanoma

  • Probably the least common melanoma but the most dangerous
  • Already thick and invasive
  • Time is of the essence for removal
  • May not be brown or black, could be red, grey, blue etc
Bowen’s Disease

  • Similar to solar keratoses. Dry scaly sometimes sore patches mostly seen on face, ears, backs of hands and forearms. In very damaged skin also on backs and legs. Rare on covered areas such as genitals and buttocks. Often discrete and localised.
  • Caused by long term sun exposure without sun protection
  • Very common
  • Low grade non-invasive form a skin cancer
  • Indicates increased risk of more dangerous skin cancer
  • Easily treated with a variety of methods depending on context from curettage and cautery, carbon dioxide peel to PDT

 

 

How common are they?

Solar Keratoses

Affect most people who have lived in Queensland most of their lives

Bowens Disease

Very common, often undiagnosed

Multifocal BCC

60% of Queensland population get a skin cancer and most are BCCs

Solid BCC

60% of Queensland population get a skin cancer and most are BCCs

Invasive SCC

Not as common as BCCs but more common than melanoma, the death rate from these is about 2/3 that of melanoma

Keratoacanthoma

I see about the same number as SCCs

Lentigo maligna

Increasing frequency, more common over the age of 50, they need wide surgical excisions and as they often appear on the face require cosmetic surgery

Superficial Spreading Melanoma

Increasing frequency with increasing age. Occur on one male in 15 and one female in 20 in Queensland. Victorian rates are about half of those in Queensland.

Nodular Melanoma

Not as common and getting less common
