Plain-English summary
A 7-year-old mixed-breed dog was diagnosed with a large mass in its lungs after showing signs of breathing problems. The dog underwent surgery to remove the tumor, which was identified as a hamartoma, a type of benign growth. After the surgery, the dog recovered well and lived for more than a year without any complications. While lung tumors in dogs are rare and often malignant, surgical removal can lead to a positive outcome if the tumor is benign.

Abstract
Primary lung tumors of mesenchymal or mixed cell origin were diagnosed in 4 dogs with clinical and radiographic abnormalities indicating an intrathoracic mass. Each dog had 1 large intrapulmonary lesion, and 1 dog also had nodules scattered throughout all lung lobes. Two dogs were euthanatized; 1 had a biphasic pulmonary blastoma; and the other had a pulmonary chondroblastic osteosarcoma with intrapulmonary metastases. The masses in the other 2 dogs were hamartomas (lipomatous in 1, microcystic in the other), which were resected. Both dogs survived more than 1 year after surgery. Primary lung tumors are uncommon in dogs and are generally malignant (adenocarcinomas or carcinomas). Tumors of connective tissue or mixed cell origin are rare, but the outcome is potentially good after surgical removal.
