Laryngeal Pharynx Adenocarcinoma in a Cat Whose Quality of Life Improved by Permanent Tracheostomy

Abstract

A laryngeal mass was palpated in a 16-year-old spayed domestic cat with progressive respiratory distress. Generally, prognosis of a laryngeal tumor in cats is poor, because no tumor specific therapy has been established, and complete dissection of the larynx may lead to serious complications. In this case, permanent tracheostomy and a less invasive, partial excision along with biopsy of the mass were performed. The mass was histologically diagnosed as a laryngeal pharynx adenocarcinoma. The cat recovered, and was discharged on day 3 after surgery. According to the owner, the cat’s quality of life was ameliorated after surgery. But the cat developed dysphagia on day 54, and died a few days later. Although the cat was severely ill, its respiratory condition was good until death thanks to the tracheostomy. Consequently, in feline cases of severe respiratory distress because of a laryngeal pharynx adenocarcinoma, tracheostomy along with partial excision biopsy is one of good options for treatment, for both patients and the owners.
