Hypersensitivity pneumonia in a schoolchild admitted to the hospital's asthma clinic.

ABSTRACT

Bird fancier's lung (BFL), also called bird-breeder's lung or pigeon-breeder's disease (PBD), is a hypersensitivity pneumonitis (HP) that is rare in children. A 9-year-old male patient complained of cough, dyspnea and chest pain, in his examination his lips were cyanosed and his SaO2 was 86% at room air. Bilateral crepitant rales and sibilant rhochi were also detected. In his thoracic computerized tomography, the ground glass areas were noted in both lungs. In his medical history, it was discovered that he lived above an office in which birds and bird manure were merchandised. Precipitant antibody level was determined. Since the levels of precipitant antibody were high and symptoms reappeared with natural provocation, our patient was diagnosed with PBD. The case diagnosed as BFL was presented in this study as an HP which should be considered in the differential diagnosis of children with respiratory distress syndrome and asthma clinic.
