mesothelioma vs adeno staining


Immunohistochemical staining and molecular testing help to confirm a diagnosis. Positive staining for calretinin, Wilms tumor-1 gene product, and cytokeratin 5/6 is associated with mesothelioma, while tumors that show immunoreactivity for TTF-1, MOC-31, and Claudin-4 staining are more consistent with adenocarcinoma.1
