[Conservative surgery of renal carcinoma in a case of synchronic bilateral involvement, with large size tumors and different histological type].

OBJECTIVE

To report a case of a large, bilateral, synchronous renal tumor.

METHODS/RESULTS: Treatment by conservative surgery achieved good results. The histological analysis showed two different carcinomas. The most most important steps of the surgical procedure are described. Renal preservation in patients with malignant tumors is discussed.

CONCLUSIONS

The case described herein is rare since the tumors were synchronous and of uncommon histological type (one of the tumors was a chromophobic carcinoma). Despite the large size of the tumors, they were successfully managed by conservative surgery.
