A Case of Chronic Pneumonitis of Infancy in a 3-Year-Old Boy / 소아알레르기및호흡기학회지

ABSTRACT

Interstitial lung disease, mostly chronic lung disorder, is usually characterized by diffuse infiltrates and disordered gas exchange, is a very rare disease in children. Chronic pneumonitis of infancy (CPI) is a recently described entity representing a distinct form of interstitial lung disease affecting infants and young children. The histologic findings suggest marked alveolar septal thickening, striking alveolar pneumocyte hyperplasia, and alveolar exudates containing numerous macrophages and foci of eosinophilic debris. A 3-year-old boy visited a local clinic with cough and tachypnea for a duration of 3 weeks. His clinical symptoms were aggravated and he was referred to our hospital. He was diagnosed with chronic pneumonitis of infancy after undergoing open lung biopsy. We herein present the case with review of literature.
