Glomus tumour is a rare tumour in animals and humans. Usually it is located in the extremities, where glomus bodies are found. Glomus tumours located in the trachea are very rare in humans and have never been described in animals. The clinical signs of a glomus tumour located in the airways are basically cough and dyspnea. These tumours are essentially benign and its resection is the treatment of choice. This paper relates a case of a glomus tumour located in the trachea of an 11 year old Cocker Spaniel dog who presented with cough, dyspnea and fever. After symptoms worsening, some X-ray plain films were done, and a 2.2cm diameter mass could be seen in the thoracic trachea. Surgical resection was done using the "torn cartilage" technique and diagnosis was confirmed by histopathology, which showed lobulated structures divided by thin conjunctive septae, with acidophil cytoplasm, hyperchromatic nuclei and scattered chromatin, both typical and atypical. The animal is fine 10 months after the surgery. There are around 15 cases descriptions of glomus tumour in humans trachea and by our knowledge, this is the first case described in Veterinary Medicine.
