case_images: It was a solid, hyperdense tumor with relatively homogeneous enhancement, peripheral hyperdensity, and a slightly lobulated margin (Figure 1, A and B).
case_images: US and tru-cut biopsies: (A) Mode B US showing an inhomogeneous solid hypoechoic mass with tiny cystic foci and lobulated margin; (B) Basaloid neoplasia - basaloid cells are interspersed with shadow (ghost) cells; (C) Area with abundant shadow (ghost) cells. HE staining: (B and C) x200. HE: Hematoxylin-Eosin; US: Ultrasonography

case_images: An ultrasound study revealed an inhomogeneous solid hypoechoic mass with tiny cystic foci, lobulated margin, and irregular borders measuring 3x2.8x2.2 cm located on the tail of the left parotid gland (Figure 2A). Tru-cut biopsies disclosed nests of basaloid cells interspersed with shadow (ghost) cells (Figure 2B). Areas with abundant shadow (ghost) cells were prominent (Figure 2C).
