A Comparative approach to phyllodes tumors in women and phyllodes-like tumors in female dogs

Mammary gland tumors, a significant concern for both humans and dogs, often carry a malignant prognosis. The diagnosis of these tumors is primarily based on their histopathological appearance in both species. This study delves into the pathological features of Phyllodes tumors in female dogs, a type not typically included in the histopathological classification of canine mammary tumors but well-documented in women. By comparing the recently described Phyllodes tumor cases in dogs with those in women, we aim to shed light on the shared vulnerability of women and female dogs to these tumors. The increasing number of studies exploring the common features between breast cancer in women and mammary tumors in female dogs makes the comparative evaluation of this rare tumor type in both species not only interesting but also crucial.
