Figure 3

The histopathological examination of the liver-biopsy specimens showed a poorly differentiated, diffusely infiltrating signet ring cell carcinoma (SRCC), grade 3. SRCC consists of signet ring cells, containing abundant intracytoplasmic mucin (arrowheads) pushing the nucleus (arrows) to the periphery. Hematoxylin-eosin stain, x40 magnification.
