Ema mesothelial cells
WebIn the diagnosis of spindle-cell pleural tumors and the fibrous form of MM and benign reactive mesothelial cell proliferation , markers of mesothelial cells are noncontributory. Immunohistochemical staining fails to identify a reactive process, but a diffuse, positive stain for EMA and the presence of protein p53 support the diagnosis of MM.
