A 71-year-old woman with loss of appetite was referred to our hospital. Imaging diagnosis revealed a large, cystically dilated left kidney with a solid tumor inside the cavity and a right hydronephrosis. A chest X-ray revealed multiple metastatic lesions. A horseshoe kidney was found intraoperatively and left nephroureterectomy with partial cystectomy was performed. Histological diagnosis was poorly differentiated transitional cell carcinoma. She died of progressive pulmonary metastases 2 weeks after operation. This is the 19th case of a renal pelvic tumor associated with a horseshoe kidney reported in the Japanese literature. The diagnosis was confounded by the extreme dilation and deformity of the hydronephrotic kidney.
