Hey everyone - thanks for the responses so far. Dan has no history of skin cancer or actinic keratosis. He has spent a fair amount of time in the sun with work and with outdoor hobbies. He has always been good about wearing sunscreen though.

As I'm sure you guys know any "different" symptom is enough to make you worry. I just don't like him to be experiencing something that I can't read about because then I don't know what do to - worry? not worry? proactive treatment? ignore it? normal? abnormal?

He does have the noraml deep tan / mild sunburn look and I expected that, but these spots are different.

Oh - Dan's not taking Advil or anything with aspirin in it.
