Botryoid Rhabdomyosarcoma : Microscopic

Comments:
Microscopic Features of Botryoid Rhabdomyosarcoma: Low magnification view of the polypoid tumor fragments which are relatively hypocellular and have abundant myxoid stroma. The cambium layer which consists of subepithelial condensed layer of tumor cells is clearly seen in some foci (see higher magnification in the next two images).
