Figure 1. Low power view showing a cellular smear with many, large groups of cells with scalloped borders (DQ).
Figure 2. There are numerous large tubulo-papillary groups with scalloped edges (Pap).
Figure 3. Cell in cell arrangement seen in some groups (Pap).
Figure 4. Cells in large groups showing mesothelial features. Nuclei are oval to round and centrally placed (DQ).
Figure 5. Abnormal mesothelial cells are binucleated with dense, central but peripherally vacuolated cytoplasm with some metachromatically staining collagen balls. (DQ).
Figure 6. Cells in large group showing mesothelial features and oval round centrally placed nuclei with prominent single nucleoli (Pap).
