Cytopathology analysis of pleural effusion aspiration: two slides using the cytospin technique were prepared, one slide was stained by Diff Quick (A) and the other was stained by Papanicolaou stain (B). Cellblock technique was performed from the sediment after concentration technique (centrifugation), and one slide was stained with hematoxylin and eosin (H&E); stains were very cellular and showed predominant malignant cells in the papillary cluster, pleomorphic nuclei, cytoplasmic vacuolization, intranuclear inclusion, and powdery chromatin in a background of few polymorphous and reactive mesothelial cells (C). Magnification in all slides is 20×
