Histological and immunohistochemical findings of hepatic EGIST. A – The tumor is composed of spindle cells (hematoxylin and original magnification 200×).B – The spindle cells show pleomorphic nuclei, commonly vacuoles beside the nuclei and abundant intercellular collagen (hematoxylin and original magnification 400×).C – The tumor cells test positive for SMA (original magnification 400×).D – Vimentin is diffusely and strongly positive in the tumor cells (original magnification 400×)
