Plain-English summary
A 12-year-old male neutered domestic shorthair cat was having trouble breathing and was breathing with his mouth open for about a month. Tests showed a large mass in his trachea (the windpipe), which was diagnosed as lymphoma, a type of cancer. He was treated with a combination of chemotherapy drugs over six months. After treatment, follow-up scans showed that the mass had disappeared, and the cat was doing well and remained healthy for over a year and a half after finishing his treatment.

Abstract
A 12 yr old male neutered domestic shorthair cat presented with worsening tachypnea of 1 mo duration and open mouth breathing. Radiographs revealed tracheal narrowing at the thoracic inlet. Computed tomography (CT) revealed a contrast enhancing 8-cm long fusiform mass within the dorsal tracheal membrane. Tracheobronchoscopy confirmed the presence of the tracheal mass at the thoracic inlet, and lymphoma was diagnosed based on uniformly atypical lymphoid cells on aspirated bronchoalveolar lavage fluid. The cat was treated with combination chemotherapy consisting of cyclophosphamide, vincristine, doxorubicin, and prednisolone. Thoracic radiographs and CT performed 1 mo after completion of the 6 mo chemotherapy protocol revealed resolution of the tracheal mass. The cat remained clinically normal at 21 mo after treatment.
