Plain-English summary
An 11-year-old mixed-breed dog was brought in for a persistent cough, and a growth in the lung was found during tests. The growth, initially thought to be a benign fibroma, was removed, and the cough improved, but it came back as the growth regrew. After two more surgeries to remove the polyp, the cough returned again, and sadly, the dog was euthanized 15 months later when the coughing worsened. Further tests revealed the growth was actually a myxosarcoma, and the dog also had two other unrelated tumors in the lungs.

Abstract
An endobronchial polyp was visible radiographically and bronchoscopically in an 11-year-old, mixed-breed dog with a persistent cough. The polyp was removed by traction. Initial histological examination suggested it was a myxomatous fibroma. The cough resolved but recurred with polyp regrowth. Two additional lung masses became visible radiographically. The polyp was removed twice more at 6-month intervals. Euthanasia was performed 15 months after first presentation when coughing recurred soon after the final bronchoscopy. Histological examination revealed that the mass was a myxomatous sarcoma. The lung contained two other unrelated tumors: a bronchioloalveolar carcinoma and a carcinoma of unknown origin.
