"Staging"
"Carcinosarcomas of the female genital tract were previously known as malignant mixed Müllerian tumours to reflect the admixed histology comprising both epithelial and mesenchymal tissue. There is now increasing evidence to show that carcinosarcoma tumour cells instead demonstrate epithelial-mesenchymal transition. Thus the 5th edition of the WHO classification of female genital tumours (2020) recommends that the term "malignant mixed Müllerian tumour" is no longer used 7."
"On imaging, it is not possible to differentiate carcinosarcomas from other ovarian neoplasms; therefore, the diagnosis is essentially based on histopathologic findings. Features common to ovarian neoplasms, in general, may be present."
