Incidental mucinous adenocarcinoma in situ of renal pelvis presenting as severe hydronephrosis

Abstract

Background: Mucinous adenocarcinoma of the renal pelvis is a very uncommon tumor, most often secondary to chronic infection and long standing irritation due to conditions such as urolithiasis. Case Presentation: Herein we report our experience with an old age male that presented with flank pain. Mucinous adenocarcinoma in situ has been discovered incidentally in his nephrectomy specimen. Conclusions: Mucinous adenocarcinoma in situ, is extremely rare and to the best of our knowledge only two cases have been reported in the English literature so far.
