Plain-English summary
A 3-year-old neutered male Australian Shepherd mix was diagnosed with lung tumors caused by a type of cancer called soft tissue sarcoma that started in his back. The cancer spread to his lungs, leading to breathing difficulties due to blockages in the airways. Unfortunately, despite treatment, the dog passed away, and further examination revealed widespread cancer throughout his body. This case highlights the serious nature of metastatic cancer in dogs and the importance of early detection and treatment.

Abstract
A 3-year-old neutered male Australian Shepherd mix dog presented with metastatic soft tissue sarcoma arising from a primary tumor in the left lumbar fascia. Two separate metastases to the lungs were characterized by neoplasia within bronchiolar walls, which caused obstruction of the bronchiolar lumina and atelectasis of adjacent alveoli, a characteristic feature of endobronchial metastasis. Neoplastic cells of the primary lumbar neoplasm, metastatic pulmonary lesions, and additional widespread metastatic masses identified postmortem were similarly immunoreactive for vimentin, but non-immunoreactive for cytokeratin, cluster of differentiation 18, synaptophysin, chromogranin, and desmin. The present report describes a naturally occurring case of endobronchial metastasis in a dog.
