A case of refractory polyarteritis nodosa successfully treated with rituximab.A 59-year-old man who presented with continuous fever, livedo reticularis, and left leg ischemia with multiple tibial artery stenosis and renal artery aneurysm, as demonstrated by arteriography, was diagnosed with polyarteritis nodosa (PAN) 6 years ago.  Although he frequently relapsed in spite of intensive immunosuppressive therapies, the disease activity of PAN was controlled with repeated rituximab (RTX) therapies and steroid doses were tapered safely.
