NEPHROGENIC ADENOMA IN CHILDREN - CASE-REPORT AND REVIEW OF LITERATURE

Nephrogenic adenoma in children is an extremely rare kind of tumor (22 cases have been described to date). We report and discuss here the ca se of a 7-year-old girl, taking into account the findings described in medical literature. In contrast to nephrogenic adenomas in adults, wh o present with this tumor in the entire ureteral tract, it has been ob served exclusively in the bladder in children so far. The most frequen t predisposing factors for the development of this tumor are extensive surgical injury such as ureter reimplantation or long-term stimuli on the urothelium caused by a foreign body. Diagnosis primarily includes sonography of the urinary tract and cystoscopy. Transurethral resecti on is regarded as the treatment of choice. Owing to the frequency of p ersistence, control cystoscopies after primary therapy are necessary.
