<s>[INST] My 13 year old daughter was just at the dermatologist for a hive like rash on her legs and arms x 3 weeks... The Dr said she thought it was her body s reaction to having the gene that can cause diabetes and/or thyroid disorders and such. She gave me a clinical term for this condition and did a biopsy. Are you familiar with this???.....and if so, what is the clinical term for this condition? [/INST] Hi....by what you quote I feel that it could be HSP - Henoch Schonlein Purpura. But skin conditions are best diagnosed and treated only after seeing them directly . I suggest you upload the image of the kid and get back to me.I wish your kid a speedy recovery. If you need any future medical consultation and suggestions, I will be glad to help. You can approach me at the following link.
