Abstract
Histopathological examination of the excised kidney specimen revealed a diffuse proliferation of tumor cells with round nuclei in the subepithelium of the renal pelvis. The tumor cells were round and mononuclear, had a high N/C ratio and irregular nuclei containing prominent nucleoli, and lymphocytes and plasma cells were admixed with the tumor cells. Based on the above histological findings and results of immunostaining, we diagnosed the tumor as a DLBCL.
