Hi it's been a while since I posted on here. My 10 year old daughter was diagnosed with cerebral vasculitis earlier this year and we are very lucky because it's only in her brain at the moment they classified it as non progressive (at the moment) so I'm assuming it can change. We are under a rheumatologist who wants to do a skin biopsy to do with her mottling which she's always had. Just curious to know if anyone else on here has had this done and what they may be looking for. She's not on any treatment yet for her vasculitis I'm assuming it's because of her age and the rarity of her having this form of vasculitis.
