In brief: Urticaria pigmentosa
Your son has an elevated number of mast cells in the skin.
When you rub the skin, the skin will make hives, because the mast cells release histamine. It doesn't mean that topical medications pose any problem to him, just that when you apply them, you need to do so very lightly, to avoid setting off histamine release. Your doctor can prescribe topical antihistamines but oral ones are really needed.

In brief: Urticaria Pigmentosa
Urticaria pigmentosa is not serious, and does not require any treatment in most cases.
However the following can be helpful: oral antihistamines mast cell stabilisers disodium cromoglicate orally may be helpful in some cases low-dose Aspirin paradoxically, this can help some patients, but must be taken cautiously as Aspirin can also worsen symptoms topical steroids.
