An 80-year-old woman was referred for evaluation and treatment of a left renal mass. An abdominal CT scan showed a 4.6 X 3.7 cm mass in the left kidney. The lesion was slightly enhanced by contrast medium. Since renal cell carcinoma could not be ruled out, radical nephrectomy was performed. The tumor weighed 190 g. Histological examination revealed Antoni A and Antoni B type schwannoma. Schwannoma is a tumor arising from the sheath of the peripheral nerves. The present case is the 6th case of schwannoma arising in the renal hilum reported in the English and Japanese literature.
