A 57-year-old female complained of left flank pain. Computerized tomographic (CT) scan revealed left renal tumor and laboratory examination revealed an extremely high serum level of CEA (815 ng/ml). No abnormal findings were recognized in gastrointestinal or genital systems. Radical nephrectomy was done.
