Would this be psoriasis?

I will occasionally get little, red patches with white scales on my body. They are usually quite small, usually no larger than a dime or maybe a nickel sometimes. It looks just like the pictures I see of psoriasis, except I never really get more than one small patch at a time. All the pictures I see on the internet show the psoriasis covering very large areas or having multiple patches covering large areas.

So, I guess I am just wonder what this is.

BTW, the patches usually occur in areas that are usually covered by clothing, but recently I got a very small one just above my eyelid, which was very strange.
