Abstract: Perianal gland tumours were diagnosed in 223 dogs through cytological and histopathological examination of samples collected from tumour-suspected masses. Of these, 102 cases were identified as perianal gland adenomas, while 121 cases were classified as perianal gland adenocarcinomas. In the analysis of tumour occurrence by breed, sex, age, and anatomical location, perianal gland adenomas were most commonly observed in non-descript and Labrador breeds, male dogs, dogs aged 5-10 years, and primarily in the perianal region. Perianal gland adenocarcinomas were most prevalent in non-descript and Spitz breeds, male dogs, dogs aged 5-10 years, and also predominantly in the perianal region. Cytological examination of the tumours revealed clusters of hepatoid cells characterized by round to oval nuclei, prominent nucleoli, and faint to deeply basophilic cytoplasm. Histopathological examination showed multiple lobules composed of sheets of hepatoid cells with indistinct cell outlines and round to oval vesicular nuclei. Notably, mitotic figures were evident in perianal gland adenocarcinomas, indicating their malignant nature.
