Localized renal cell carcinoma of an unusually large size: case report.
Renal cell carcinoma has a variable clinical course. Size is a prognostic factor correlated with venous invasion, lymph node or distant metastases. These are more often encountered when the size exceeds 10 cm. For 20 years, incidental renal tumours have represented the majority of diagnosed cases, as a result of more common use of imaging techniques. We report a case of renal cell carcinoma of an unusually large size, without metastatic or locally advanced disease. Histology revealed a pT2 clear cell renal cell carcinoma of 31 x 31 x 10 cm, which was totally resected. It is the first case reported of localized conventional renal cell carcinoma reaching such a size.
