This case report reminds us that vasculitis is an inflammatory  process that attacks blood vessels leading to organ dysfunction. The etiology can be a hypersensitivity reaction (think drugs) or an IgA mediated process secondary to infection (Strep or Mycoplasma). In this case, concomitate use of NSAIDS (very common etiology of hypersensitivity) and Mycoplasma lead to vasculitis. Treatment ranges from supportive care, to steroids to immunosuppressive agents such as azathioprine.
