As I have been learning more about the many types of vasculitis I am curious about my sons diagnosis. A few years ago he was told after biopsy etc he had 'leukocytoclastic vasculitis' probably as a reaction to his body trying to fight off strep. He needed no treatment other than elevating his legs for 5 weeks till the rash resolved and close monitoring of kidney function for 2 years which was all clear. He must take antibiotics whenever he gets a sore throat to head of future reactions and so far has had no further flares. However , I have recently been researching the condition a lot more and I am wondering if there might be a more specific diagnosis. No named type was ever mentioned that I have seen on lists like the one on the website - I understand what ' leukocytoclastic' refers to - but is it a definition of the trigger typical of one or several types or is it the type but is another name for say ' hypersensitive vasculitis'. I'm not sure if I'm explaining the question too well. Is leuko a characteristic of a named type or is it the type. Is leuko the same or connected to ANCA? Phew!
