Metastatic Prostate Adenocarcinoma Posing as Urothelial Carcinoma of the Right Ureter : A Case Report and Literature Review

الملخص EN

This is a case report of a 67-year-old patient with distant metastasis of prostate cancer to the right ureter which caused hydronephrosis.

At the beginning, both of the cytology of the morning urine and imaging findings were consistent with urothelial carcinoma.

Nephroureterectomy was subsequently performed.

Interestingly, the pathological examination of the excised ureter revealed that the malignancy was derived from the prostate.

No skeletal metastasis was detected.

However, after four months of follow-up, several abnormal signal shadows were reported in skeletal scintigraphy and the prostate specific antigen (PSA) was gradually increasing.

We present such a case for its unique presentation.

A review of the literature is also provided.
