title: [Synchronous bilateral chromophobe cell renal carcinoma: a case report].
abstract: An 81-year-old female presented with abdominal discomfort. Computed tomography scan showed a 26 x 22 mm tumor in the left kidney and 43 x 37 mm tumor in the right kidney. Clinical diagnosis was bilateral renal cell carcinoma, left; cT1a, right; cT1bN0M0. We planned primary unilateral partial nephrectomy, followed by secondary contralateral radical nephrectomy. Left partial nephrectomy was performed and 4 months later, laparoscopic right renal nephrectomy was performed without serious postoperative renal dysfunction. Pathological diagnosis of both tumors was chromophobe renal carcinoma. The patient has been doing well without any evidence of recurrence or metastasis.
