Abstract
|
|
|
|
Pulmonary masses were observed in the thoracic cavity of a 9-year-old female Korean native cattle (Hanwoo) encountered at a Jeju, Korea slaughterhouse. Grossly, the thoracic cavity was filled with pulmonary masses. Histologically, the neoplastic masses were composed of many abnormal papillary structures lined by single to double columnar neoplastic cells and formed arborizing fronds supported by significant fibrovascular stroma. The neoplastic cells showed strong destructive and infiltrative growth to adjacent tissues and were strongly positive for pan-cytokeratin (CK), CK 7 and sporadically positive for CK MNF116. The masses in the female Hanwoo were diagnosed as a papillary pattern of pulmonary adenocarcinoma.
