Summary  Pulmonary alveolar microlithiasis is a rare disease characterized by intra-alveolar deposit of calcium and phosphate concretions. Presentation in children is very unusual given its chronic progression over several years, with marked clinical-radiological dissociation. In its pathogenesis is involved a gene, recently described, encoding a sodium phosphate co-transporter expressed in lung tissue. Usually evolves from an asymptomatic stage of variable duration, adding coughing and difficulty breathing, determining respiratory failure and cor pulmonale in advanced stages. A pediatric case illustrating clinical features and difficulties in diagnosis is reported.
