(A) B-mod ultrasonography: the lesion was detected as a well-defined, oval-shaped, hypoechoic mass (red arrows) with slight posterior enhancement (dashed blue arrows) and measured 18 x 20 x 24 mm. (B) Colour Doppler US examination revealed vascularity in the lesion.

The mass measured at 15 x 20 x 25 mm in the upper outer quadrant of the left breast showed posterior acoustic enhancement (Fig. 1A). Color Doppler US examination revealed increased vascularity in the lesion (Fig. 1B).
(A) In the color coded elastogram of the lesion region, it was observed that there was a blue, yellow, and red (hard) mosaic pattern. (B) Shear wave elastography: The elasticity score is measured as 7,04 m/s-146,48kPa.

In the color coded elastogram of the lesion region, it was observed that there was a blue (soft), yellow, and red (hard) mosaic pattern (Fig. 2A). In SWE, the highest elasticity value in the lesion was 7.04 m/s-146.48 kPa (Fig. 2B).
The tumour shows uniform spindle cells growing in fascicles with intervening bands of ropey collagen (A) H&E, x100). In immunohistochemical analysis, the tumor cells show diffuse and robust positive staining [(B) vimentin, (C) desmin, and (D) CD34 (x200)].
