Plain-English summary
A 9-year-old female Siamese cat was brought to the vet with a firm, reddish mass about 2 cm in size on her abdomen that had been growing for about a month. The vet performed a partial mastectomy to remove the tumor, and further tests confirmed it was a tubulopapillary carcinoma, a type of mammary gland cancer. Unfortunately, mammary tumors in cats are often more challenging to treat than in dogs, and this case highlights the need for careful monitoring and follow-up.

Abstract
Mammary tumors in felines rank third in frequency after skin tumors and lymphoma, equivalent to 12% of the total cases of neoplasia in felines and 17% in female cats; however, remission and histopathological diagnosis in small animal practice is considerably lower, unlike what happens with canines, where mammary and skin tumors are the main cases of remission and diagnosed neoplasia in laboratories. This paper reports the case of a nine-year-old female Siamese cat that was treated at a private clinic. The patient had a mass located in the abdominal mammary gland of about 2 cm in diameter, of a reddish color, firm consistency and serous secretion, with an estimated evolution time of one month, removed through partial mastectomy. The sample was fixed in buffered formalin at 10% and processed for histopathological analysis at the pathology laboratory of the University of Nariño, using routine hematoxylin and eosin. In addition, it underwent a Periodic acid-Schiff (PAS) differential staining and an immunohistochemical marker estrogen receptor (ER), which tested negative. Thus, it was diagnosed with tubulopapillary carcinoma in mammary gland, this being the first reported case of this disease in the Department of Nariño.
