Macroscopic and microscopic findings of SFT. Macroscopically, the tumor mass was firm and yellowish-white with an intact capsule (13.3 cm maximum diameter) (a). Microscopically, the tumorous tissue showed a proliferation of oval to short spindle-shaped cells arranged in a “pattern-less pattern” (H&E × 400) (b). Immunohistochemically, the tumor cells were negative for CD34 (× 400; c), but positive for STAT6 (nuclei, × 400) (d) and vimentin (× 400) (e). Ki67 labeling index was < 5% (× 400) (f)
