An ultrastructural analysis of vascular leiomyoma of the bladder.
We report a case of vascular leiomyoma of the bladder in a 62-year-old man. To our knowledge, this is the first ultrastructural study published on vascular leiomyoma of the bladder. The tumoral cells reproduced the smooth muscle cells. The vascular structures corresponded to capillaries and arterioles. We consider that the vascular component is not tumoral and its origin is related to mast cells.
