The pathologic image of myxofibrosarcoma. (A) Low power image: Spindle tumor cells are arranged in interwoven bundles, with large density and compact arrangement (haematoxylin–eosin, original magnification: 4 ×). (B–D) High power image: the nucleus of the tumor is large, hyperchromatic, and heteromorphic. Mitosis is more common, and giant tumor cells are seen (haematoxylin–eosin, original magnification: 10 × , 20 × , 40 ×)
