Because of the rarity of epithelioid smooth muscle tumors, criteria predictive of their malignant behavior are less well established than those for spindle-cell smooth muscle tumors. 72 In an old study of 26 cases, small size, expansile margin, presence of clear cytoplasm, extensive hyalinization, and lack of tumor cell necrosis were parameters
