Clear cell “mesonephric” carcinoma of the bladder. a Hematoxylin and eosin stain demonstrating characteristic clear cell appearance of the neoplastic cells (arrow). b Cytokeratin 7 staining diffusely positive in neoplastic cells (arrow). c Cancer antigen 125-positive in neoplastic cells (arrow). d P504S/α-methylacyl-coenzyme A racemase is positive in neoplastic cells (arrow). e Cytokeratin 20 is only focally positive in neoplastic cells (arrows). f Carcinoembryonic antigen is focally positive in neoplastic cells (arrow). g Thyroid transcription factor 1 staining is negative.
