Abstract:

Aim: Multiloculated cystic renal cell carcinoma is a rare variant of renal cell carcinoma. Incidence and biological behaviour of the tumor are unknown and bilateral cases are very rare. Case report: Fifty four-years- old male patient was admitted to the Urology policlinic with a left flank pain which was present during one month. On ultra sonographic examination solid hypoecoic mass 37x 32 mm in size and extending to the adrenal area were found at the upperpole of right kidney. Another mass 38x34 mm in size, with mixt nature and smooth contours and finely vascular flow were detected in middle-upper pole of the left kidney. The patient had a urinary stone history. On CT scan; each kidney were normal in size and a cystic lesion 3.5 cm in diameter and with thickened wall was located on cortical-parapelvic region of the upper half of the left kidney. Exophytic elongated cystic lesion was also observed on right kidney upper pole which had a thick superolateral wall. Conclusion: Right radical and left partial nephrectomy were performed. On macroscopic examination; lesions with many cysts were detected in both kidneys which were diagnosed histopathologically as multiloculated cystic renal cell carcinoma
