Itchy Rash On Arms, Legs, Raised Papules, Foul Smelling Stools. Causes And Treatment?

I have an extremely itchy rash on the extensor surfaces of both my arms and legs. There are multiple raised red papules that are spread about a centimeter away from eachother. I also have foul-smelling stools . Celiac s disease was on the top of my differentials list; however, a few doctors I went to said that the rash did not look like dermatitis herpetiformis . Can you give me a few differentials that matches itchy rash on extensor surfaces of the arms and legs so that I can google image it and perhaps have an idea as to what is going on. Thank you!

Hello,
Welcome to healthcare magic.
The differential diagnosis I can think of from your description are an Id eruption, follicular psoriasis, follicular lichen planus and also dermatitis herpetiformis. ( though you mentioned that it has been ruled out). A skin biopsy would help to confirm the diagnosis.
Hope this could throw some light on your problem.
Take care.
