A,The tumor predominantly consists of spindle cells admixed scattered multinucleated cells and abundant ropey collagen. B, Foccally, in striking myxoid stroma, the cells are scarcely diffused, and the vascular pattern varies from plexiform to dilated intermediate-sized vessels. C, The multinucleate cells have hyperchromatic, pelmorphic and florte-like muclei. D, Scattered inflammatory cells, such as lymphocytes and plasma cells could be seen in myxoid stroma.
