title: Cyanosis due to pulmonary arteriovenous malformation.
abstract: Cyanosis is frequently encountered in the neonate or infant. Most often it is due to congenital heart disease or primary lung disease. Pulmonary arteriovenous malformation is an unusual cause of cyanosis. Polycythemia and clubbing are associated findings. The treatment is excision or embolization if the disease is not too extensive.
