Mammary tumours of dogs and cats are among the most commonly observed neoplastic changes after skin and lymphoid tissue tumours (Viste et al., 2002). The etiology of feline mammary tumours are not well identified, they are more commonly seen in female cats while being rare in the male (Bostock, 1986; Hahn and Adams 1997). Cat mammary tumours are mostly malignant upon microscopic examination, and are generally seen in cats of 10 years of age without showing any breed predisposition (MacEwen et al., 1984). In this report a papillary cystic adenocarcinoma that was observed in the mammary gland of a Van cat together with its histopathological and immunohistochemical findings is described.
