Abstract:
Objective To discuss the clinicopathologic and imaging features of multilocular cystic renal eell carcinoma(MCRCC). Methods The data of 8 cases(5 men and 3 women)MCRCC classified according to 2004 WHO criteria were reviewed retrospectively.The tumor was incidentally found in 5 out of 8 cases.Renal ultrasound and CT scans were available in all 8 cases.CT or enhanced CT scans showed a well-defined cystid mass with irregular thickening wall or septa in 7 cases,without visible nodules found.For treatment,open or laparoscopic radical and partial nephrectomy was done in those cases. Results Postoperative pathological findings confirmed the diagnosis of MCRCC.The mean greatest diameter of the tumors was 5.6 cm.Microscopically,the wall and septa lined by one or several layers of clear cells were observed in all cases.The TNM stage of all 8 cases was T1 N0 M0.For pathologic grade,7 cases were G1 and 1 case was G2.Seven patients were followed up and remained tumor free during the average time of 8 months. Conclusions MCRCC is an uncommon subtype of RCC,it has a lower malignant potential and a better prognosis compared with other types of RCC according to the literature.Nephron-sparing surgery may be an appropriate treatment option for MCRCC.
