Webarea between the nuclear lobes. C-ANCA is most commonly associated with Wegener’s granulomatosis. The perinuclear pattern (P-ANCA) is an artefact of alcohol fixation of the neutrophils which causes cytoplasmic antigens to redistribute around the nucleus. The P-ANCA pattern is less specific than C-ANCA because of its association with a wider ...
