Idiopathic pulmonary hemosiderosis is characterized by a triad of iron-deficiency anemia, hemoptysis, and radiographic diffuse lung infiltrates. However, the inconsistent initial presentation in children may cause a significant delay in diagnosis. Autoimmune reactivity seems to be the most acceptable theory of pathogenesis. We reported an 8-year-old boy presenting with a cough, fever, and difficulty breathing with a history of iron-deficiency anemia and an abnormal autoimmune response in the last 3 years. Perinuclear antineutrophil cytoplasmic antibodies were positive and chest computed tomography revealed patchy ground glass haziness. Bronchoalveolar lavage fluid showed hemosiderin-laden macrophages. The respiratory symptoms improved with oral corticosteroids.
