Abstract Cutaneous arteritis (CA) is a rare limited form of polyarteritis nodosa (PAN), which usually has a benign prognosis and requires less aggressive therapy. Here, we present a case of CA localized to both skin and muscle limited to the same area as skin lesions. We propose CA with muscle disorders as a severe subtype of CA and present a literature review of CA with muscle disorders, which may require treatment with intravenous pulse methylprednisolone, immunosuppressive therapy, and below‐the‐knee amputation. Our case presented here demonstrates a severe case of CA associated with compartment syndrome, leading to a highly elevated serum concentration of procalcitonin.
