Resumo

Background: Tracheal tumors are rare and may cause obstruction of the trachea. The neoplasms most commonly diagnosed in cats are lymphosarcoma, squamous cell carcinomas and adenocarcinomas. Surgical resection may provide a clinical cure for small, benign and localized tumors. For malignant neoplasia, surgery is usually palliative. Tracheal segment excision is an invasive procedure, particularly when the intrathoracic trachea is involved, and this increases the risk of stenosis, surgical suture dehiscence, necrosis and pneumothorax. Intraluminal tracheal stents have been used in dogs with tracheobronchomalacia, presenting a feasible alternative to surgery for the treatment of tracheal lumen obstruction.Case: A 11-year-old male mixed-breed cat was referred to the Veterinary Hospital of the Federal University of Rio Grande do Sul (HCV-UFRGS) with a history of appetite loss, wasting and progressive inspiratory dyspnea, for the last 30 days. The cat presenting with oral breathing. Radiography of the lateral thorax shown a radiopaque area, 1cm in diameter, superimposed in the tracheal region, close to the carina cartilage, at the fourth intercostal space. A tracheoscopy confi rmed the diagnosis of tracheal neoplasia, which was identifi ed as an adenocarcinoma by biopsy and histopathology. Given that surgical resection may result in signifi cant morbidity and consequent mortality, the
