The 72-year-old man with left renal tumor detected by computed tomography was referred to our department for the detailed examination of associated polycythemia. Polycythemia disappeared and the serum erythropoietin became decreased after left radical nephrectomy. Histopathologic examination revealed clear cell renal cell carcinoma(G2>G1>G3, INFb, v1, ly0, eg, fc1, im0, rc-inf0, rp-inf0, s-inf0, pT2a). Immunohistochemical study revealed erythropoietin expression in the carcinoma cells. Although post-operative course had been uneventful, development of the nodule in the right lung was observed at 9 postoperative month. Video assisted thoracoscopic surgery was performed and histopathological examination of the resected tumor confirmed metastatic renal cell carcinoma. The patient has remained disease-free to date.
