Figure 2 CT of the abdomen showing multiple low-attenuating metastatic lesions in both right and left hepatic lobes. VideoGIE 2018 3, 31-33DOI: (10.1016/j.vgie.2017.09.012) Copyright © 2017 American Society for Gastrointestinal Endoscopy Terms and Conditions

Figure 3 FNA sample from liver lesion shows single and loose cohesive clusters of tumor cells with moderate amount of vacuolated cytoplasm, pleomorphic nuclei with irregular nuclear contours, and small nucleolus, characteristic of adenocarcinoma. A few small clusters of benign hepatocytes are present. Diff-Quik stain, orig. mag. × 400.

Figure 4 FNA sample from pancreas mass showing loose cohesive clusters of tumor cells with moderate amount of vacuolated cytoplasm and pleomorphic nuclei with irregular nuclear contours and small nucleolus, consistent with adenocarcinoma. Single tumor cells are present. Diff-Quik stain, orig. mag. × 200.

Figure 7 CT scan of abdomen showing a heterogenous mass occupying almost the entire right lobe of the liver. VideoGIE 2018 3, 31-33DOI: (10.1016/j.vgie.2017.09.012) Copyright © 2017 American Society for Gastrointestinal Endoscopy Terms and Conditions

Figure 8 FNA sample from liver mass showing single and cohesive clusters of tumor cells in a background of necrosis. The tumor cells have dense cytoplasm, high nuclear-to-cytoplasmic ratios, and hyperchromatic nuclei with irregular nuclear contours, consistent with neuroendocrine tumor. Occasional mitoses are seen. Diff-Quik stain, orig. mag. × 200. VideoGIE 2018 3, 31-33DOI: (10.1016/j.vgie.2017.09.012) Copyright © 2017 American Society for Gastrointestinal Endoscopy Terms and Conditions

Figure 9 FNA sample from liver showing single and dyscohesive clusters of tumor cells in a bloody background. The tumor cells are small and uniform, and have high nuclear-to-cytoplasmic ratios and eccentrically located oval nuclei with inconspicuous nucleolus, consistent with squamous cell carcinoma.
