A 76-year-old man with bronchial asthma was admitted for respiratory failure and bloody sputum. A significant drop in haemoglobin and multiple consolidations supported clinical diagnosis of diffuse alveolar haemorrhage (AH). Myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) was positive and urinalysis suggested glomerulonephritis. Based on eosinophilia, sinusitis, peripheral nerve involvement, and leukocytoclastic vasculitis, he was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA) associated with AH. Our case-based review suggested that male predominance (65%), high positivity for ANCA (88%), and a high frequency of renal involvement (45%) may be characteristic of AH in EGPA. Although AH is rare in EGPA, we should be aware of this life-threatening complication.
