case_images: Patient underwent transurethral resection of the prostate (TURP), and pathology revealed a dominant population of neoplastic spindle cells intermingled with giant neoplastic cells and multifocal necrosis that involved almost the entire tumor (Figures 1(a), 1(b)).
case_images: Immunohistochemistry demonstrates that tumor cells express smooth muscle actin (a) and vimentin (b).
