Tracheal Tumors

18 Tracheal Tumors



Leslie E. Fox



1. What are some of the most common tumors of the trachea in the dog?

Tumors of the trachea are rare and are typically malignant except for benign osteocartilaginous tumors associated with the tracheal rings in young dogs.


2. What is the typical signalment for dogs with tracheal tumors?

Dogs with tumors of the trachea are middle age to older with no gender or breed predilection. Dogs with osteochondromas are most often younger than 1 year old.


3. What are the typical clinical signs exhibited by dogs with tracheal tumors?

Because of partial airway occlusion, a progressive worsening of dyspnea, wheezing, coughing, and exaggerated expiratory effort are the most common clinical findings. Acute onset severe respiratory distress with cyanosis may be the primary presenting complaint.


4. What are the differential diagnoses for partial tracheal obstruction?

Polyps, abscess or granuloma, foreign body, vascular anomalies, collapsed tracheal rings from trauma, nodular amyloidosis, papillomatosis, and a granulomatous reaction to Filaroides osleri.


5. How are tracheal tumors diagnosed?

Auscultation of the trachea during physical examination may help identify the presence of a partial obstruction through localization of higher pitched airway sounds (wheezing or stridor) at the site of tracheal narrowing. Plain radiography may help delineate the location of the tumor; however, direct visualization of the mass with a bronchoscope is most useful. Histopathology of biopsy tissue samples obtained through the biopsy channel of the endoscope is usually sufficient to confirm a diagnosis.
