IT looks like your skin is pretty fair, eh?

From a little bit of research, it seems that you might be experiencing actinic keratoses, also known as solar keratoses. During this skin condition, small rough or scaly areas of skin appear due to damage from sun exposure. Some actinic keratoses can turn into squamous cell skin cancer, so it is important to perform self-examinations often and catch them early. You might also want to insist on seeing a skin specialist. A dermatologist is better qualified to diagnose the lesion and to decide if a lesion should be biopsied or treated.

I have recently started to collect information about this blemish and inevitable skin cancer keeps cropping up. I’ve looked at actinic keratoses; I don’t think my blemish is scaly, it may look like that because of the deep wrinkles and it doesn’t feel rough (as sandpaper) but is quite smooth like the surrounding skin when I stretch the skin.

I agree the advice to regular monitor the blemish; during my reading the idea of taking digital photos is also good.

The doctor did look closely and didn’t see cause for concern; but I think later I will press for a dermatologist to have a look. I may even arrange to see a local clinic about non surgical cosmetic applications to temporary hide the blemish, it’s in rather a prominent place and their dermatologist may also be able to give me a definite name for the blemish.

Sounds like a plan. Please let us know what the dermatologist says. I'd be interested to see if s/he can help you with temporary cover up and longer term diagnosis.
