Organizing pneumonia ( OP ) is a clinicopathological entity that occurs idiopathically or in association with several conditions, but there are few reports about myeloperoxidase anti‐neutrophil cytoplasmic antibody ( MPO ‐ ANCA )‐associated OP . We describe a patient with OP whose clinical conditions improved spontaneously. Moreover, serum MPO ‐ ANCA titers paralleled the clinical activity of the disease, which disappeared in association with disease quiescence. Based on these findings, a subset of patients may have OP related to MPO ‐ ANCA . ANCA testing should be considered in the work‐up of patients with suspected OP .
