Abstract:
Most renal tumours arise from renal parenchyma. Urothelial
carcinomas constitutes less than 10 % of renal tumours. Less
than 1% of renal pelvic epithelial malignancies are
adenocarcinoma [1]. Mucinous adenocarcinoma (MA) of
renal pelvis is extremely rare and constitutes less than 0.3% of
renal pelvic tumours [2]. We report a case of mucinous
adenocarcinoma of crossed ectopic renal pelvis occurring in
association with pyonephrosis secondary to obstruction by a
large staghorn calculus.
