Histopathological investigations of six true-cut biopsies for the same mass seen on computed tomography scan. Hematoxylin and eosin (H&E) stains for different samples (a–c) illustrating hypercellular spindle cell lesions, with the nuclei of some cells resembling those of smooth muscle origin, with mild cellular pleomorphism and nonsignificant count of mitotic figures. The cellular population was positive for CD10 (d), smooth muscle actin (e), and estrogen receptor (f)
