Extensive ischaemic colitis-like colonic lesions in eosinophilic granulomatosis with polyangiitis

Eosinophilic granulomatosis with polyangiitis is a rare, immune-mediated, multisystemic disorder belonging to the group of antineutrophil cytoplasmic antibody-associated vasculitides. Gastrointestinal symptoms are relatively common in patients with eosinophilic granulomatosis with polyangiitis, reportedly occurring in ∼22.3% of cases. Vasculitic necrotising lesions normally occur in the intestinal tract, and in the present case, the colonic lesions were remarkably severe and extensive. Pulse steroid therapy combined with cyclophosphamide improved the patient's condition without any serious complications, such as intestinal perforation.
