Inverted papilloma of the upper urinary tract is a rare lesion and the differential diagnosis with transitional cell carcinoma is really hard. A case of 49 year-old male with recurrent right flank pain is reported. Excretory urogram suggested a filling defect involving the right mid ureter and bilateral retrograde pyelogram that confirmed a solitary filling defect in the right mid-ureter, while selective urinary cytology was positive for transitional cell carcinoma G1. Conservative therapy was carried out and 2 years follow-up with several excretory urograms and ultrasound studies revealed no recurrence.
