Adenoma de glândula mucosserosa de traqueia em felino

Abstract

Adenoma of the mucoserous gland was presented in an elderly feline with progressive and specific clinical signs, notably cough, dyspnea and strictures. Tracheal tumors are rare in humans and animals, with few reported cases, with adenocarcinoma, chondrosarcoma, mastocytoma, lymphoma and lymphosarcoma being the most commonly described tumors. Infections caused by opportunistic microorganisms may occur secondary to the tumor. The diagnosis of tracheal tumor can be made through imaging tests, such as cervical and thoracic radiography, tracheoscopy, computed tomography and magnetic resonance imaging. In this case, the images obtained by the tomographic examination were essential for the diagnosis, in which a mass located inside the trachea was evidenced, associated with wide stenosis of the tracheal lumen. The chosen treatment was surgical removal of the mass and the affected tracheal rings. The exercise material was sent for histopathological analysis, confirming adenoma of the mucoserous gland. The clinical history, clinical signs, and CT and radiographic results were similar to previously reported cases of tracheal tumors in this species, with the CT examination being essential for the conclusion of the case.
