ABLAÇÃO DO CANAL AUDITIVO VERTICAL EM FELINO COM CARCINOMA CERUMINOSO - RELATO DE CASO

Abstract

Within the clinical routine of dogs and cats, otological disorders add up significantly, with their causes varying significantly. Within this series, neoplasms can be significant and adenocarcinoma in the ear canal is one of the most common tumors in this location, with felines being the most affected species, especially elderly animals. The present study aimed to report the case of a feline diagnosed with ceruminous gland carcinoma. A 10-year-old cat, SRD, with a history of recurrent otitis was treated. The animal underwent a surgical procedure of ablation of the vertical ear canal, removing the neoplasm completely, which was sent for histological examination, which diagnosed ceruminous cell carcinoma. After 50 days of the surgical procedure, the patient underwent a new evaluation and showed no signs of neoplasm recurrence. Thus, it is suggested that ceruminous gland carcinoma should be considered as a differential diagnosis in cats with a history of chronic otitis, especially in elderly animals, corroborating the importance of using otoscopy to evaluate the ear canal, to recommend a diagnosis in the stage’s disease onset. Ear canal ablation proves to be effective for the treatment of ceruminous gland carcinoma, and it is important to know where the tumor originates, to determine whether it is a total ablation of the ear canal or just the vertical canal.
