Very Mild Dermatitis Herpetiformis Or Unrelated Rash?

I have looked at pictures and it seems like dh usually has blisters... I have had this rash on my abdomen for 1 yr +, and I'm now wondering if it's related. It kind of looks like it could be a very very mild form but I dunno if it can happen without blisters... What do you guys think?
