Renal Cell Carcinoma in a Great Simple Renal Cyst: A Case Report

The tubule of the kidney or renal cyst is called a dilated duct. Congenital and acquired renal cystic disease develops in the nephron and collecting channels. Renal cysts are common in the way or as a segment, can be seen as unilateral or bilateral. In simple cysts, the diagnosis can easily be made. The most important diagnostic problem, with a tendency to malignancy,of complex cysts,and simple cysts, is to distinguish the correct format. Suspicion of malignancy are thickened, calcified, irregular septa and contrast fixation. Simple renal cysts with underlying renal cell carcinoma (RCC) in a relatively small number of cases have been reported in the literature. We aimed to present this caseof a 36-year-old female patient in our clinic, evaluated with cambered complaint Bosniak type 2 diagnosis of cystic lesions. The lower pole of the left renal pelvis was large enough to fill a simple abdominal cyst with underlying renal cell carcinoma, without any additional disease in the upper left abdomen and lower part of the kidney. Excision of the cyst was carried out and the laparascopic postoperative pathology reported a RCC. In our patient an integral surgical radical nephrectomy was performed. This case highlights the importance of recognizing simple renal cysts which may form in the RCC. Therefore, further research should be considered in the presence of atypical findings. Although no cases of cystic RCC, with all advanced radiological examinations, could not be preoperatively diagnosed, in RCC cases diagnosed with suspected pathology, radical nephrectomy should be done.
