Figure 3 Macroscopic and histological findings of the tumor tissue. A: The resected specimen was an 8.5 cm × 6.5 cm × 5.5 cm encapsulated tumor; B: Macroscopic findings indicated that the cut surface of the resected tumor was yellowish and greasy; C: Histologically, the tumor comprised uniform primitive mesenchymal cells in an abundant myxoid stroma with delicate, branching, chicken-wire capillary vasculature (original magnification: 100 ×; scale bar: 100 µm); D: Most areasof the lesion exhibited low cellularity. Although round to oval nonlipogenic cells were dominant (original magnification: 400 ×; scale bar: 50 µm); E: Small amounts of Oil Red O-positive lipoblasts were also detected (original magnification: 400 ×; scale bar: 50 µm).
