Abstract

Here we describe two cases of papillary urothelial neoplasm of low malignant potential in adolescent boys. One case was a 16-year-old boy with a polypoid mass beside the right ureteral orifice and the other case was a 13-year-old boy with a papillary mass beside the left ureteral orifice. The initial presentation was hematuria in both cases and the bladder mass was detected by ultrasonography. Complete resection of the bladder tumor was performed by using an 11-Fr pediatric resectoscope. Follow-up has been performed with urine analysis, urine cytology, and bladder ultrasonography or cystoscopy every 3 months with no evidence of recurrence.

  FIG. 1 Ultrasonograph of case 1. Markers indicate the presence of a urothelial tumor on the posterior bladder wall.

• 

  FIG. 2 Endoscopic view of a urothelial tumor in a 13-year-old boy (case 1). Transurethral resection (A, C) was performed with an 11-Fr pediatric resctoscope and TUR equipment (Karl Storz GmbH, Tuttlingen, Germany). Deep biopsy was performed (B). Resected bladder tumor (D).

• 

  FIG. 3 Histologic examination showing round to oval shaped, uniformly enlarged nuclei; inconspicuous nucleoli; and rare mitosis in case 1 (H&E, ×400). These findings are compatible with papillary urothelial neoplasm with low malignant potential.

• 

  FIG. 4 Bladder ultrasonography (A) and microscopic examination (B; H&E, ×200) of a 16-year-old boy (case 2).
