Start as itchy, small, dark, circular indentations with what looks like a tiny dot in the centre, on my lower legs and now my arms, they itch at first and are painful when scratched, eventually afte a few months the majority of them fade and leave a completely flat, white area which does not tan in the sun, I think the pigment has gone! They are now all over my lower legs and arms, they look terrible. My mother had the same (hers were much larger than mine) and many years ago she was sent to a dermatologist who took a sample and told her it was Australian Leg - an allergy to the sun! She was given no treatment and that is why I have ignored mine, but they look so bad now I am embarrassed. What do you think they could be.
