Description
Summary:Laryngeal and tracheal tumors are rare in pets; some piece of information on their disease behavior, therapy and evolution are limited. Neoplasms in this area are a diagnostic challenge. In many cases, they can be biopsied and excised using endoscopic instruments, but there is no report of this in canines. The goal of this study is to report a successful case of a laryngeal neoplasm removal through endoscopy. A head and neck radiogram revealed a mass in the laryngeal lumen protruding into the trachea. The patient then underwent an endoscopy to confirm the radiographic diagnosis and to surgically remove the tumor. The histopathological diagnosis was poorly differentiated carcinoma. The most appropriate treatment for laryngeal tumors is the resection of the submucosa or a partial laryngectomy however, partial and total laryngectomies are associated with many postoperative complications. In contrast, the endoscopic approach allows for highly magnified visualization of the lesion in situ, which facilitates the surgical removal of the mass through videosurgery. With little manipulation of the affected area, the chances of postoperative complications are reduced, leading to a more rapid recovery. Key words: tumor, larynx, canine, endoscopy. Tumores de laringe e traqueia sao raros em animais de estimacao e as informacoes sobre o comportamento, terapia e evolucao destas neoplasias sao limitadas. Neoplasias nesta area sao desafios diagnosticos. Em muitos casos, pode ser feita a biopsia e excisao da massa utilizando instrumentos endoscopicos, mas nao existe relato deste tipo de procedimento em caninos. O objetivo deste estudo foi relatar um caso de sucesso da remocao endoscopica de um tumor de laringe. A radiografia da regiao cervical revelou uma massa na luz da laringe invadindo a traqueia. O paciente foi entao submetido a uma endoscopia para confirmar o diagnostico radiografico e remover cirurgicamente o tumor. O diagnostico histopatologico foi de carcinoma pouco diferenciado. O tratamento mais adequado para os tumores da laringe e a resseccao da submucosa ou uma laringectomia parcial, no entanto, estas estao associadas a muitas complicacoes posoperatorias. Em contraste, a abordagem endoscopica permite a visualizacao da lesao in situ, o que facilita a remocao cirurgica da massa atraves de videocirurgia. Com pouca manipulacao da area afetada, as chances de complicacoes pos-operatorias sao reduzidas, levando a uma recuperacao mais rapida. Palavras-chave: tumor, laringe, canino, endoscopia.
