A patient with previously treated, temporal artery biopsy proven, giant cell arteritis (GCA) developed lower extremity ulcers and sensory neuropathy. Sural nerve biopsy showed epineural vessels with focal mild chronic inflammation. The lower extremity skin and nerve abnormalities improved after retreatment with prednisone. The rare manifestations of lower extremity skin and peripheral nervous system involvement associated with GCA are discussed. GCA must be considered in lower extremity ischemic processes of the skin and peripheral nervous system.

Vasculitis affecting the peripheral nerves predominantly manifests as subacute, progressive, asymmetric sensorimotor polyneuropathy or mononeuritis multiplex, and more rarely as painful mononeuropathy, pure sensory neuropathy, neuropathy of the cranial nerves, plexopathy, or as autonomic neuropathy. Vasculitic neuropathy may occur isolated or non-isolated (systemic) together with involvement of other organs. Systemic vasculitis with involvement of the peripheral nerves is further subdivided into primary (Takayasu syndrome, giant cell arteritis, classical panarteritis nodosa, thrombangitis obliterans, Kawasaki disease, Churg-Strauss syndrome, Wegener granulomatosis, cryoglobulinemic vasculitis, Behcet disease, microscopic polyangitis, Schoenlein Henoch purpura) or secondary systemic vasculitis (autoimmune connective tissue diseases, vasculitis from infection, sarcoidosis, malignancy, drugs, radiation, or diabetes). In addition to routine laboratory investigations and nerve conduction studies, nerve biopsy is essential for diagnosing the condition and to delineate it from differentials, although its sensitivity is only approximately 60%. Therapy of non-viral vasculitic neuropathy is based on corticosteroids and cyclophosphamide alone or in combination. Additional options include azathioprine, methotrexate, mycophenolate mofetil, or rituximab. In single cases immunoglobulins, immunoadsorbtion, or plasma exchange have been successfully applied. In case of virus-associated vasculitis interferon-alpha plus lamivudine or ribaverin may be beneficial.
