My son who will be 4 next week has had weird spots on and off since last September. There is no other way to describe them. They have appeared basically all over his body (arms, legs, trunk and even face). They sometimes itch a bit but not excessively. He also has eczema. He has been seen by 3 different GPs, none of them knew what it was but weren’t concerned. I’ve also had him seen by two private dermatologists, again didn’t know what it was. They took photos and showed colleagues and none of them knew either. He doesn’t have any other symptoms really (although sometimes my hypochondriac self looks for things and wonders is he quite tired/run down etc). Interestingly the spots seem to flair up when he has any sort of cough or virus. The private dermatologist said it was likely some sort of atypical viral exanthem. Just really looking to see if anyone has had similar?
