Abstract
We report an unusual case of a urothelial tumor on a ureteral polyp without hydronephrosis. The patient was a 50-year-old male. He had experienced several episodes of gross hematuria. Cystoscopy revealed a tumor that periodically prolapsed into the bladder. The tumor had a smooth-surfaced stalk with an erythematous, edematous lesion at the end. Tomography showed a mass and filling defect at the left ureterovesical junction. The results of urine cytology tests were negative. After the tumor was identified as a urothelial carcinoma by frozen biopsy analysis, a ureteroscopic resection was performed. The final pathological diagnosis was urothelial carcinoma arising in a ureteral polyp. No recurrence of the tumor or polyp was observed at the 3-month follow-up. To our knowledge, this is the first report in the Korean population of a urothelial tumor arising from a ureteral polyp.
