Macroscopically, the tumor presented as a beige, firm and well-demarcated mass A. The histology shows a cellular proliferation of bland, clumsy, and monomorphic spindle cells in a collagenous background with focal dystopic calcifications, and a partially storiform growth pattern. Increased mitotic activity, necrosis and atypia were not apparent, also no epithelial component was noted. 4x (B), 10x (C) and 20 × magnification, all hematoxylin and eosin (H&E) stainings (D)
