Pigeon Fancier's Lung in Children

Pigeon fancier's lung occurred in 3 children whose fathers kept pigeons. The clinical features included progressive breathlessness, cough, cynanosis, sweating, and inspiratory râles. Chest x-rays showed diffuse fine mottling. The serum gave positive precipitin tests to pigeon serum or droppings in each case. 2 cases were treated with steroids, but the importance of breaking the contact with pigeons is stressed.
