Plain-English summary
A 14-year-old male Domestic Short Hair cat was brought in with a single mammary tumor about one centimeter wide, diagnosed as invasive micropapillary carcinoma, a type of aggressive cancer. After surgery, it was found that the cancer had spread to nearby lymph nodes. The cat lived for 10 months after the diagnosis, with a period of 7.5 months without signs of the disease. This case emphasizes the need for quick and thorough treatment for mammary tumors in male cats, as they can be quite serious.

Abstract
We describe the case of a 14-year-old Domestic Short Hair male cat that presented with a single mammary tumour one centimetre in diameter, classified as invasive micropapillary carcinoma. Histology and immunohistochemistry revealed a high mitotic index, a KI-67 index of 10%, a lack of reactivity to myoepithelial markers, and a dense infiltration with T and B lymphocytes at the periphery of the tumour. Micrometastases were detected in the regional lymph node at the time of surgery. Overall survival time was 10 months with a disease-free interval of 7.5 months. Distant metastases in the sublumbar lymph nodes confirmed the aggressiveness of this tumour, which has recently been subtyped in female cats. This is the first case reported in male cats with a complete follow-up, highlighting the importance of prompt and aggressive treatment in the presence of mammary tumours in male cats.
