[Transitional cell tumor in a 12-year-old patient].
Transitional cell papillomas, which are tumors of epithelial origin, are the most common urinary tract neoplasm in adults but are extremely rare in children. In both groups the main location is the bladder, often around one of the ureteric orifices. Symptoms vary widely but the most frequent is gross hematuria. Transitional cell papillomas are histologically low-grade tumors and total excision is considered curative. However the rate of recurrence in the literature is high, and there is a potential for a more aggressive type of tumor. We report the case of a 12-year-old girl who presented with a transitional cell papilloma near the right ureteric orifice and describe the etiopathogenesis, diagnosis, treatment and outcome of this entity.
