  FIGURE 3. Pathology tumor imaging. (A) Low power HE staining showing a monomorphic spindle‐to‐epithelioid cell population arranged in interlacing fascicles, with hemangiopericytoma‐like vasculature. (B) High power HE staining showing tumor cells with vesicular chromatin and prominent nucleoli. (C) CD99 immunostaining. (D) TLE3 immunostaining. (E) BCL2 immunostaining.
