The macroscopic specimen was solid and grayish with smooth margins (Fig. 2).
Pathological findings (magnification x200). The tumor was a 30 x 23 mm tumor with atypical spindle cells arranged in a fascicular histoid pattern. Immunohistochemistry demonstrated that the tumor cells were positive for alpha-smooth muscle actin (alpha-SMA), desmin, and vimentin. a Hematoxylin-eosin staining. b alpha-SMA. c Desmin. d Vimentin

Postoperative histopathology revealed a 30 x 23 mm tumor with atypical spindle cells arranged in a fascicular histoid pattern (Fig. 3a). Immunohistochemistry demonstrated that the tumor cells were positive for alpha-smooth muscle actin (alpha-SMA), desmin, and vimentin (Fig. 3b-d).
