A 45 year old male reported with flank mass which on evaluation was found to be gross hydronephrosis containing multiple nodular lesions. Nephroureterectomy was done with a diagnosis of urothelial cancer in a hydronephrotic kidney. Various pathological tests confirmed MEST. Mixed epithelial and stromal tumor (MEST) of kidney often arises centrally in the kidney and grows as an expansile mass. Most of the tumors are solid and many have cystic areas. MEST presenting as multiple polypoidal lesions in a grossly dilated kidney due to pelvi ureteric junction obstruction (PUJO) has not been reported so far.
