Pathological findings in the large intestine in patients with eosinophilic granulomatosis with polyangiitis (EGPA) (a–c) or chronic eosinophilic pneumonia (CEP) (d–f). Evidence of bleeding was present in the submucosa (a). The number of eosinophils in the submucosa was higher in patients with EGPA (a–c) than in those with CEP (d–f). Edematous changes (expressed as the width of the basement membrane-to-crypt distance or the crypt-to-crypt distance) were more severe in patients with EGPA than in those with CEP
