case_images: These two patterns were intermixed at places and had a sharp demarcation at some foci (Figure 1).
case_images: Arginase highlighting the HCC component and was negative in neuroendocrine component (Arginase, 20x).

case_images: On IHC, Arginase (Figure 2) and Hep par was positive in some of the neoplastic nodules.
case_images: Synaptophysin showing membranous positivity in the neuroendocrine component and was negative in the HCC component, with a sharp demarcation between two components (Synaptophysin, 20x).
