Fig 2 (A) Magnetic resonance imaging shows a 1.7-cm sixth thoracic vertebral mass. (B) The spinal cord is compressed by the anterior extension of the atypical mass. The Annals of Thoracic Surgery , DOI: ( /j.athoracsur ) Copyright © 2011 The Society of Thoracic Surgeons Terms and Conditions

Fig 3 (A) The uterine mass from 2003 exhibited cellular leiomyoma showing hypercellularity. There was no pleomorphism, necrosis, or obviously increased mitotic activity (α-smooth muscle actin, original magnification ×400). (B) The uterine mass from 2006 shows same findings as in panel A (α-smooth muscle actin, original magnification ×40). (C) The rib mass shows proliferation of highly cellular spindle cells between bone (α-smooth muscle actin, original magnification ×100). (D) The tumor cells show strong immunoreactivity for progesterone receptor (original magnification × 400).
