From: Myoepithelioma-like tumor of the vulvar region: a case report in China and review of the literature
The tumor was a well-circumscribed nodule, focally encased by a fibrous pseudocapsule (a). In nonmyxoid patterns, the spindle-shaped tumor cells formed storiform arrangements, with a combination of hypocellular and hypercellular areas (b-c). The fibrous area shows deposition of hyalinizing collagen fibers (d). In myxoid patterns, epithelioid tumor cells proliferated singly or in a loosely cohesive reticular manner (e), In high power field, the epithelioid tumor cells resembled rhabdomyoblasts (f)
