Skin spots on neck and back (light brown)

Patient: I have light brown spots on my neck and back, not too severe, but it’s annoying enough. I know sun exposure isn’t the reason, because i’m not that often in the sun. What else could this be? I know I have vitamin D deficiency.

Symptoms: The spots aren’t bothering me at all.. but I have skin writing disease aswell, so that’s itching like crazy, unless I take my medicine. loratadin
