case_images: Microscopic examination revealed a cellular proliferation of neoplastic cells arranged haphazardly, in cords (Figure 1), occasional nests, and focally palisading (Figure 2) and separated by regularly spaced arborizing fibrovascular septa within an extracellular myxoid matrix (Figure 3) with occasional myxoid pool formation (Figure 4).
case_images: Focal areas with palisading are identified within the tumor (H&E, 100x).
