case_images: The cystoscopy found a large bladder mass, located in the trigonal area and left lateral wall on the dome of the bladder, as well as necrotic-looking floating lesions (Figure 2).
case_images: histological aspect of resected mass that widely infiltrated by spindle cells: A); in a myxoid stroma accompanied by an inflammatory cell infiltrate (H and E, x100); B); spindle myoepithelial cell proliferation (H and E, x400)
