Case 1 is a 49 year old male who visited our clinic with the chief complaint of right flank mass. IVP showed deformity of right renal pelvis and calyces and tumor vessels were outlined in the right kidney by aortography. Transperitoneal nephrectomy was done under the diagnosis of right renal tumor and histopathological findings revealed clear cell carcinoma. A rice grain-sized nodule at left buccal mucosa, which was noticed one year previous to the first visit was found to be a metastatic lesion by biopsy. Metastatic lesion was removed and followed by radiation treatment.
