Gross examination shows infiltration of the adenal gland, renal plevis and macroscopic vascular invasion. A: (H&E, 200×) Spindle like shaped tumor cells with small eosiniphilic cytoplasmn and pleomophic nuclei with eosinophilic nucleoli. Interspersed small amounts of histiocytes and small lymphocytes. The amount of eosinophils is not elevated in viable tumor areas. B: (H&E, 400×): Areas of tumor necrosis withs rims of histiocytes and increased number of eosinophils.
