Histological review. (a) The border between pleomorphic area and myxoid area observed in the NCCS099 sample (Dmin=0.46 to myxofibrosarcoma) (hematoxylin and eosin stain). (b–d) Histology of the NCCS102 sample (Dmin=0.50 to leiomyosarcoma). This tumor showed marked pleomorphism (b) hematoxylin and eosin stain, but tumor cells were positive for desmin (c) and αSMA (d). (e) Fibrosarcomatous fascicular area seen in the NCCS104 sample (Dmin=0.39 to fibrosarcoma) (hematoxylin and eosin stain). (f) Epithelioid structure observed in the NCCS097 sample (Dmin=0.56 to MPNST) (hematoxylin and eosin stain).
