FIGURE 1.

Distribution of vasculitis, neutrophilic dermatosis, and ANCA type assays in a French cohort of 17 patients (A) and in the whole cohort of 50 patients including 33 additional patients from a literature review (B). There were significantly more PG cases in GPA patients than in other forms of vasculitis (76% vs 36%; P = 0.02). ANCA = anti-neutrophil cytoplasmic antibodies, C = cytoplasmic fluorescence, EED = erythema elevatum diutinum, EGPA = eosinophilic GPA, GPA = granulomatosis with polyangiitis, MPA = microscopic polyangiitis, MPO = myeloperoxidase, P = perinuclear fluorescence, PG = pyoderma gangrenosum, PR3 = proteinase 3, SS = Sweet syndrome.
