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.
