Hemoptysis is the expectoration of the hemorrhage originating from the tracheobronchial tree or lung parenchyma. Cardiac, pulmonary, hemoatological pathologies, infectious or systemic diseases and idiopathic pulmonary hemosiderosis can cause hemoptysis. Idiopathic pulmonary hemosiderosis is a rare cause of diffuse alveolar hemorrhage in children that results in abnormal hemosiderin deposition in the lung parenchyma. It is generally seen in children under 10 and most commonly between 1 and 7 years. While gender distribution is even in childhood, it is more frequently seen in males in adulthood. Diagnosis is confirmed by identification of hemosiderin-laden macrophages in broncho-alveolar lavage and ruling out other causes of intra- and extrapulmonary hemorrhage. Here we present a rare case of IPH that became symptomatic in adolescence. IPH should be considered in the differential diagnosis of patients who present with respiratory symptoms and particularly hemoptysis in childhood and adolescence with positive chest imaging findings
