Role of cystitis glandularis and intestinal metaplasia in the development of a bladder benign polypoid tumor in a pediatric patient (case report)

Benign tumoral bladder tumors in children are extremely rare. The inflammatory condition determined by the presence of glandular cystitis and intestinal metaplasia, coexisting or separately, can be a determinant factor for the development of these bladder masses. Both entities have been suggested to represent a precursor for bladder adenocarcinoma. We present the case of an autistic adolescent that presented with a polypoid bladder mass and urinary tract infection. We performed a cystoscopic examination and biopsy of the tumor and due to the large dimensions and preliminary histological results we decided to perform a laparotomy and excision of the mass and bladder wall that was attached to. Post operatory evolution and follow-up showed no recurrence or progression of the dysplasia towards adenocarcinoma.
