[Two cases of metastatic renal tumor].

In this report, two cases of metastatic renal tumor are described. The first case is a 58-year-old female who had branchiogenic carcinoma. She had found a left neck tumor, before asymptomatic macrohematuria developed. The second case is a 25-year-old female who had choriocarcinoma. She had no urological symptoms. In both cases, unilateral nephrectomy was performed. Seventy nine cases of metastatic renal tumor in survivals have already been reported.
