title: [An unusual case of macroscopic hematuria in pediatric age].
abstract: An unusual case of macroscopic hematuria in a 14 year old boy is presented. At the time of the first hospital admission, no urinary tract infection could be demonstrated, in spite of the associated symptoms of stranguria and dysuria. At ultrasound examination, only a mild thickening of the upper bladder wall was detected, and cystoscopy showed a huge oedema and inflammation of the mucosal layer. The biopsy of the bladder was characterized by a definite eosinophilic infiltration; due to this particular hystologic pattern, the diagnosis of eosinophilic cystitis was made. In the following months, the boy did not improve. Recurrent hematuria occurred, and a pseudo-polypoid mass in the inner bladder wall was detected at ultrasonography. A limited resection of the vesical dome was performed, to remove completely the mass. The hystologic examination showed Schistosoma Haematobium eggs in the bladder wall, with a typical granulomatous reaction. The post-operative course was uneventful, and the child was completely cured after Praziquantel treatment. The Authors underline the need to take into account Schistosomiasis in cases of hematuria, particularly when this symptom affects boys coming from countries where Bilharziasis is endemic.
