[Transitional cell tumor of the bladder in children: report of a case].

Transitional cell tumours of the bladder in children are exceptionally rare. This paper presents a new case in an 11-year old patient. The benignity of these tumours during the paediatric age can be verified due to the low infiltration incidence; some authors, however, describe cases of relapses which are commented upon. The careful follow-up that has to be done in this type of patients is underlined.
