Tracheal osteochondroma in a dog.
A young female Labrador Retriever-type dog had a 4 1/2-month history of respiratory distress, which eventually became severe, leading to cyanosis. Physical examination suggested an upper airway obstructive lesion, which was confirmed by bronchoscopy and radiography to be a mass in the thoracic portion of the trachea. The mass was removed surgically and, on histologic examination, was found to be an osteochondroma. Six months after surgical extirpation, there was no indication of recurrence of tumor.
