Plain-English summary
An 8-year-old Persian cat was diagnosed with a serious uterine tumor after an ultrasound revealed a large mass in the right uterine horn. The tumor was invasive and had spread to other areas in the abdomen and chest. This type of tumor, known as a malignant mixed Müllerian tumor, is rare in cats and has features similar to those found in human cases. Unfortunately, due to the advanced nature of the disease and its spread, treatment options may be limited, and the prognosis is often poor.

Abstract
A homologous malignant mixed Müllerian tumor of the uterus occurring in an 8-year-old Persian cat was described with regard to its clinical and pathologic features. A polypoid multinodular mass of the right uterine horn was shown by an ultrasound examination. Grossly, the right uterine horn was enlarged because of a vegetative and infiltrating tumor, grayish-white in color, that penetrated the uterine wall to the level of the perimetrium. Many metastatic nodules were found in abdominal and thoracic cavities. Histologically, the neoplasm had both carcinomatous and sarcomatous components and was diagnosed as an uterine malignant mixed Müllerian tumor. This is the fourth case reported in cats. The histologic features and proliferation rate of this tumor were similar to the corresponding human neoplasms, which occur mainly in postmenopausal women. The possible hormone dependence of the tumor is briefly discussed.
