A pulmonary hamartoma was found in a 5 weeks over term Jersey Holstein cross bull calf. A 36 x 22 x 22 cm, spongy, pale pink mass with a distinct lobulated pattern was continuous with the left caudal lung lobe and compromised other thoracic viscera. The mass was non-cystic and uniformly consisted of soft, pink tissue. Histologically, the mass consisted of a disproportionate number of bronchiolar and alveolar structures, arranged in a haphazard pattern. Ascites, localized subcutaneous oedema, and chronic passive congestion of the liver were additional findings.
