Abstract
- A multilocular cyst of kidney is a rare pathological entity, which has been reported in the literature under several names. These various names reflect the controversy surrounding their nature. This tumor is traditionally regarded as benign in nature and a nephrectomy has to be performed because of the difficulty in its accurate diagnosis. Malignant recurrence of a multilocular cyst of kidney has an even rarer incidence, with only a few cases having been reported. We report a case of 50-year-old male, with an incidentally detected right renal cystic mass. This mass was pathologically confirmed as a multilocular cyst of kidney after a radical nephrectomy, which locally recurred as a malignant mesoblastic nephroma.
