Anemia as the sole presenting symptom of idiopathic pulmonary hemosiderosis: report of two cases.

Idiopathic pulmonary hemosiderosis (IPH) is a rare disease in children and has an unknown etiology. It is characterized by the triad of hemoptysis, pulmonary infiltrates on chest radiograph (CXR) and iron deficiency anemia. We report two young children, aged 3 and 4 years, were admitted due to pale-looking appearance but without hemoptysis or other respiratory symptoms.

Clinical analysis of necrotizing pneumonia in children: three-year experience in a single medical center.

Necrotizing pneumonia (NP) is a rare but complex complication of lobar pneumonia in children. It is characterized by massive necrosis and liquification of lung tissues by the presence of multiple cavities rather than a solitary one. To evaluate the clinical features of NP, we enrolled 17 patients at Chang-Gung Memorial Hospital (Kaohsiung) from November 1999 to December 2002.
