Rash Experts?

If you know what this is, please comment in the comment section below or email me. This kid has had this for about ten days. It is mainly on both temples, his neck and one shoulder. Nowhere else. We got some scabies type lotion; that is not working.

It could be heat rash, but it is hot here all the time so is he stuck with the rash until he moves back to Minnesota? He does not try to scratch it at all. Weird. Haitian Doctors are not experts at white-kid rashes. ANYONE?????? Good and bad guesses welcome.
