Primary neoplasms of the trachea are uncommon in dogs and cats. Patients are often middle aged or older, except dogs with osteochondromas. Clinical signs consistent with tracheal obstruction, including dyspnea, wheezing, stridor, and cough, are common. Caution should be used during diagnostics and therapeutics to prevent respiratory embarrassment. Survey radiography often reveals the mass, and bronchoscopy allows direct visualization and sampling of the lesion. Options for treatment include surgical excision, chemotherapy, radiation therapy, or some combination of these methods. Most tumors respond well to complete surgical excision, although lymphoma responds best to chemotherapy, with or without adjunctive radiation therapy. Data on long-term follow-up are not available, but prognosis most likely depends on tumor type and stage.
