Summary

We present a 47-year-old Caucasian fire fighter who developed multisystem organ failure in the setting of a positive antineutrophil cytoplasmic autoantibody (myeloperoxidase) as well as confirmed Rocky Mountain spotted fever by skin biopsy PCR. This case provided a diagnostic challenge, a rare association of a Rickettsia infection and autoimmune vasculitis as well as a unique management approach.
