ABSTRACT

Background:

Primary tracheal adenocarcinoma is a rare neoplasm in cats. The clinical signs often are indicative of upper airway obstruction accompanied with dyspnea, stridor, wheezing, exercise intolerance, and cough. The severity of the clinical signs is related to the size of the mass and consequently, the proportion of the tracheal lumen that is obstructed. The diagnosis is made using thoracic radiography and tracheobronchoscopy by collecting fragments for histopathological analysis and removing the mass. The present study aimed to report the case of a cat with tracheal adenocarcinoma. Case A 17-year-old Persian female cat presented with clinical signs of dyspnea and progressive weight loss. Emergency therapy was started with bronchodilators, antibiotics, and corticosteroids, but there was no response to treatment. Complementary blood and imaging tests were performed. Thoracic radiography revealed soft tissue opacity overlying the dorsal trachea from the third to the fourth rib, bronchial pattern, and pulmonary hyperinflation. Tracheoscopy showed an irregular intraluminal thoracic trachea mass, occluded by approximately 95% of the airway lumen. The mass was biopsied multiple times with endoscopic cup biopsy forceps, followed by removal of approximately 50% of the mass lesion with an endoscopic wire snare. The patient was in intensive care, and since her clinical condition worsened 48 h after the endoscopic procedure, euthanasia was performed. Necropsy revealed a remanescent mass located in the trachea lumen 8 x 3 mm and a nodule in the right caudal pulmonary lobe with 8 mm of diameter . Histological examination showed epitelian cuboidal neoplastic cells with acinar patterns. Only a few mitosis and moderate anysocitosis were observed. The final diagnosis was primary tracheal adenocarcinoma with pulmonary metastasis...(AU)
