well it has been known
Photodermatitis caused by something like euphorbia and sun give discrete blisters. Rubbing against a plant that causes inflammation would usually give a more diffuse pattern.
I get bruised easily, and a pattern like that would have me wondering what I had banged into. When I am diving, the weight belt blocks usually give me bruises on the hips and legs, so that after two weeks I look like I've been beaten up.
