The macroscopic and microscopic findings and immunohistochemical staining of the uterine mass: a Macroscopically, the cut surface presented as a gray-white colored mass, with a “worm-like” appearance (red arrows). b Microscopically, the uterine large myoma presented spindle-like smooth muscle cells without atypia and mitosis. c and d The tumor showed a growth of benign leiomyomatous tissues within vascular vessels (C, H&E; D, Elastica van Gieson). e Immunohistochemically, the tumor was positive for α-SMA
