Mesonephric-like Adenocarcinoma of the Female Genital Tract: Novel Observations and Detailed Molecular Characterisation of Mixed Tumours and Mesonephric-like Carcinosarcomas.

Our observations provide additional evidence that MLAs have a Müllerian origin and characterize mesonephric-like carcinosarcomas in which chondroid elements appear to be characteristic. In reporting these findings, we provide recommendations for distinction between a mesonephric-like carcinosarcoma and a MLA with a spindle cell component.
