Vasculitic phase CSS in kidney. A, note the necrotizing granuloma in the upper part of the field and the necrotizing vasculitis in the lower part of the field, both superimposed on a background of eosinophilic inflammation in a patient with asthma and eosinophilia. Although described as the classic picture of CSS, in modern biopsy material this combination of features, either in a single site, or merely scattered in different areas of the biopsy, is actually uncommon. B, another small vessel showing fibrinoid necrosis. (A: H and E, 200 ×; B: H and E, 400 ×)
