RESUMO
Non-keratinizing squamous cell carcinoma of the trachea was diagnosed in an 11-year-old domestic shorthaired cat suffering from progressive cough and dyspnoea. The tumour was characterized by immunohistochemical expression of cytokeratins and focal expression of vimentin. The cat was exposed historically to high concentrations of environmental cigarette smoke and this may have been a contributory aetiological factor in the genesis of this tumour.
