Picture
This man has been a heavy smoker for many years.   The white thickening is scarring from the smoking and there is early Leukoplakia within this scarred area that requires close followup as it can easily change to become and squamous cell carcinoma.  Clear message - DO NOT SMOKE as it increases the incidence of ALL cancers.

Picture
Man in his fifties with this sore on his forehead that has been present for at least 12 months.  This lesion is 2 cm across and will require a flap procedure to close the defect.
Clear message - any skin that doesn't heal within a month needs to be presumed to be a skin cancer unless proved otherwise

Picture
Typical serpentine blood vessels indicating that this lesion is likely to be a Basal Cell Carcinoma

Picture
This teddy bear is on a mans thigh and has been there a long time.  You will notice that the pigment pattern is regular and because the pigment is brown and black it means it is only in the epidermis.  This is a Congenital Nevus and is of no concern

Picture
Beware the persistent ulcer on a tongue. If this was present for longer than one month, it requires a punch biopsy because of the possibility of it being a squamous cell carcinoma

Picture
This lesion on the upper lip has been present for a few months and was examined with the dermatoscope and looks like it is just scar tissue.  The picture below is of the same lesion without any pressure from the dermatoscope and you can see the blood vessels that allow the diagnosis to be made.

Picture
This lesion consists of skin coloured clods with central blood vessels with a uniform pattern.  This has the features of a Seborrheic Keratosis. Old terminology describes this as a cobblestone appearance

Picture
This spot has a dark black clod centrally with a grey smudge around 9 o'clock.  This is a piece of rusty steel under the skin

Picture
This beautiful flower shows central ulceration with surrounding white thickening related to keratinisation and is likely to be a Squamous cell carcinoma.
