Abstract

We describe a 66-year old patient with a recurrent ulcer on her right ankle. Biopsy revealed medium-vessel vasculitis consistent with cutaneous polyarteritis nodosa. There were no signs or symptoms suggestive of systemic vasculitis, but a 18FDG-PET scan showed areas of increased uptake around the large arteries and the pelvic and shoulder girdles. These findings suggested polymyalgia rheumatica in the setting of large-vessel vasculitis. This case thus supports the statement from the Chapel-Hill consensus conference that classification of systemic vasculitis by vessel size is based on the vessels predominantly involved, but vessels of other sizes may also be affected.
