Idiopathic Pulmonary Hemosiderosis: An Unexplored Cause of Treatment Refractory Pediatric Iron Deficiency Anemia

Abstract

Idiopathic pulmonary hemosiderosis (IPH) is an unusual cause of pediatric iron deficiency anemia (IDA) characterized by alveolar hemorrhage leading to hemosiderin deposition and fibrosis in the lungs. Though the typical triad of presentation is hemoptysis, IDA, and lung opacities on thoracic radiographs, often the sole manifestation of IPH may be severe IDA in children.
