[Transitional cell carcinoma of the ureter with an inverted growth pattern which was accompanied with bladder tumor:...

The patient was a 75-year-old man who complained of macrohematuria which had set in from April 12, 1988. Under the clinical diagnosis of bladder tumor, total cystectomy with ureterosigmoidostomy was performed on June 25. During his surgery, we discovered a polypoid lesion of the right ureter close to the common iliac artery. The tumor was peanut-sized and had a stalk suggesting benign nature, so we resected it. Postoperative pathological examination revealed the tumor was transitional cell carcinoma (grade 2) with an inverted growth pattern. Though we could find no signs of tumor recurrence, the presence of tumor's residuum could not be ruled out. We performed nephroureterectomy of the right side on December 19. Follow-up on July 1, 1989 this patient revealed no tumor recurrence.
