[A case of synchronous ipsilateral renal cell carcinoma and renal pelvic urothelial carcinoma (collision tumor): a case report].
A 54-year-old woman consulted our hospital with the complaint of microscopic hematuria and proteinuria. Abdominal computed tomographic scan revealed a tumor mass on the lower pole of the left kidney. Left radical nephrectomy was performed under the diagnosis of renal cell carcinoma. The pathological diagnosis was a collision tumor consisting of renal cell carcinoma (clear cell type, G3, INFalpha, pT1b, v -) and urothelial carcinoma of the renal pelvic (G3 >> G2, pT3, ly + , v +). Postoperative chemotherapy was not given. Convalescence was uneventful and one year after the operation she is alive with no recurrence or metastasis.
