4. 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).
