Rash

My 23 month old has had a rash on his legs for over a year now. The rash is not contagious because no one else in the family has it. We also don't have any animals. 7 dermatologists have looked at him and can't figure out what it is. They want to take a biopsy of it to see if they can figure out what it is. This involves them cutting his leg and stitching him back up. Before I agree to this I thought I would post some pics to see if any of you have ever seen anything like this. The pics are of his legs. This is the inly place the rash is and it has not spread. Any answers would be appreciated.

    No one has mentioned food allergies? Or chemical sensitivity to laundry detergent or dryer sheets?

    We can't use dryer sheets, my daughter and I break out, we use dryer balls that reduce static.

      That kinda resembles ringworm, which makes circular looking rash, easily treatable. I hope you figure it out.

        Is there something new in his diet?

          They thought ringworm at first but then after 3 months of treatment and it wouldn't go away they decided it wasn't that. He only breaks out on his legs. No where else.

          What material has he been wearing on his legs? What soap have you been using in his bath?

              try making green smoothies and see if it will change. The body is a funny thing, sometimes it only needs good nutrition that can handle the problem . The body heal its self but you have to feed it raw vegan stuff.

                He developed the rash over a year ago now and I have changed his diet, his clothing and the laundry soap but nothing seems to work. I was just hoping that maybe someone had seen it before.

                The first photo looks like a rash a couple of mine had when it was allergy related.
