·      Henoch-Schönlein pupura

·      Vasculitis associated with collagen vascular disease

·      Serum sickness and cutaneous vasculitis syndrome

·      Hepatitis C-associated essential mixed cryoglobulinemia

·      Hepatitis B-associated polyarteritis nodosa       

2.  產生ANCA(antineutrophilic cytoplasmic antibody)

·      Wegener’s granulomatosis

·      Churg-Strauss syndrome

·      Microscopic polyangiitis

3.    T細胞免疫反應+形成granuloma

·      Giant cell arteritis

·      Takayasu’s arteritis

·      Wegener’s granulomatosis

·      Churg-Strauss syndrome
