Abstract

Background In 1990 The American College of Rheumatology (ACR) established criteria for the classification of vasculitis. Cutaneous vasculitis (CV) comprises a wide and heterogeneous group of entities.

Objectives Our aim was to revise the usefulness of ACR-1990 criteria in classifying patients with CV.

Methods Retrospective study of a wide and unselected series of patients with CV from a single university hospital from January 1976 to January 2012. Patients were classified according to the 1990 ACR methodology and criteria.

Results 773 Patients (351 women/422 men) with a mean age of 34.1±27.4 years were diagnosed as having CV.

Applying the 1990 ACR criteria patients were classified as secondary to connective tissue diseases (n=35), major infections (n=27), malignancies (n=16), mixed essential cryoglobulinemia (n=13), Wegener Granulomatosis (n=3), Churg-Strauss syndrome (n=3) and Polyarteritis nodosa (n=3). The remaining 673 patients were classified as Hipersensitivity vasculitis (n=247; 36.6%) or Henoch Schönlein Purpura (n=414; 61.4%). Disappointingly, 127 (18.8%) met criteria for both entities and 12 out of 673 cases did not meet criteria for HV nor HSP and were not classified.

Conclusions The ACR-1990 criteria for vasculitis do not properly classify patients with CV.
