title: Pulmonary hamartoma and multiple cardiac anomalies in a Finn-Dorset cross lamb.
abstract: A case of pulmonary hamartoma was diagnosed in a neonatal, male, Finn-Dorset cross lamb with concurrent cardiac anomalies and palatoschisis. On gross examination, the lungs were markedly enlarged and spongy. Histologically, pulmonary lobules were composed of severely dilated and hyperplastic terminal bronchioles, separated by an abundant connective tissue stroma. Alveoli were generally absent. Other bronchi were hypoplastic and lacked both cartilage and smooth muscle. Both the cranial and caudal vena cavae and the pulmonary veins entered the right atrium. This anomaly has not been previously reported in lambs.
