Ureteral Ewing's sarcoma in an elderly woman: A case report
1Department of Urology, the First Hospital of China Medical University, Shenyang 110001, Liaoning Province, China.
Background:
Ewing's sarcoma (ES) is regarded as a skeletal tumor, with few instances of extra-skeletal ES. A primary ES in the ureter is extremely rare.
Case Summary:
We report the case of a 69-year-old woman who presented with intermittent flank pain and hematuria and was found to have a mass in the left ureter. Pathology of the excised mass indicated ES. The clinical treatment and pathologic characteristics in this case, and a review of the literature describing ES in the urinary system, are presented.
Conclusion:
Due to the rarity and malignancy of ES in ureter, early diagnosis and prompt surgical treatment are critical.
