Primary pulmonaryneoplasia (PPN) is a relatively uncommon but important cause of pulmonary disease in dogs, representing approximately 1% of all canine tumors. 1 , 2 , 3 Most of these tumors are malignant, with benign lesions

In cats, primary pulmonaryneoplasia (PPN) is uncommon. Respiratory signs are typically not present until late in the disease course, and cats may also have nonspecific signs such as weight loss
caudal lung lobe was suspected. The primary differential diagnosis for this patient was spontaneous tension pneumothorax secondary to pulmonaryneoplasia. Other potential differential diagnoses for the suspected left caudal pulmonary mass included
noncardiogenic pulmonary edema was diagnosed. Differential diagnoses for the intratracheal soft tissue nodule included tracheal foreign body, extension of pulmonaryneoplasia, tracheal neoplasia, and granuloma.

Differential diagnoses for the intrathoracic mass include primary pulmonaryneoplasia of the accessory lung lobe, or metastatic pulmonaryneoplasia. However, considering
