Mucinous cystadenocarcinoma of renal pelvis presenting as pyonephrosis

الملخص EN

Mucinous cystadenocarcinoma of renal pelvis is a rare epithelial tumor with poor prognosis.

It is postulated to arise from metaplastic glandular mucosa in response to chronic irritation, and comprises less than 0.3 % of total renal pelvic tumors.

We present this case of a tumor noted in a 45-year-old lady that was diagnosed as mucinous cystadenocarcinoma on histological examination after radical nephrectomy.

The patient is remaining well over a followup of three months.
