65 Years, Male, Pleural effusion right side, for cytology. Protein: 35 g/l, Sugar: 19 mg/dl. Cells: 1620/cmm. I think these look more like mesothelial cells, though they are in large numbers. What would you call this ? Reactive Mesothelial cells ? Mesothelioma ? Or Mets from Adenocarcinoma ? Thanks.
