Abstract:
Bird fancier's or breeder's lung is an unusual hypersensitivity pneumonitis found in pediatric patients, due to avian antigen inhalation. A case of pigeon breeder's lung in a 12 years old child is presented. Clinical symptoms were dry cough for 15 days, dyspnea and weight loss. Physical examination of the patient showed cyanosis, chest tightness, tachypnea, inspiratory crackles and oxygen saturation of 91% in room air. Laboratory data revealed hypergammaglobulinemia and elevated LDH. Pulmonary function testing showed a mixed ventilatory pattern and a decreased carbon monoxide diffusion (DLCO) capacity. Radiological findings were compatible with hypersensitivity pneumonitis, and pigeon IgG antibodies (ELISA) and skin tests with pigeon serum were positive. The child improved with corticoid therapy and antigen avoidance.
