In this study, the sebaceous gland adenocarcinoma was presented in the external auditory canal of a 10-year-old female tabby cat. There were three tumoural masses located macroscopically in the external auditory canal in the dimensions of 0.2 × 0.5, 0.3 × 0.5, and 0.1 × 0.1 cm, and they were of hard consistency. The cut sections of these tumoural masses were of multilobular appearance and ranged from white to yellow colour. Histopathological examination revealed the presence of oval or round shaped tumour cells with hyperchromatic nuclei and cytoplasmic lipid vacuoles that were divided by fibrous tissue into lobules. Atypism and mitosis were not significant. Irregular necrotic areas and mononuclear cell infiltrations composed of lymphocytes and histiocytes were also observed. In conclusion, our laboratory service confirms that the sebaceous gland adenocarcinoma is a rarely occurring tumour in cats with specific histopathological lesions.
