[A case of metastasis of renal cell carcinoma to the abdominal wall 13 years after nephrectomy].

A 68-year-old man was admitted to our hospital complaining of a tumor of the left abdominal wall. Thirteen years previously, had undergone a nephrectomy of a right renal cell carcinoma with T2, N0, M0, manifestations stage I. Prior to his second operation, a parenchymal tumor was strongly suspected. The tumor, however, was finally diagnosed pathologically as being a metastatic renal cell carcinoma. Postoperatively, the patient has been well for 21 months without any evidence of recurrence at the time of this report. Long-term follow-up is thought to be essential for cases of renal cell carcinoma with a slow-growing type of metastasis.
