title: Unusual bladder masses in children.
abstract: Benign and malignant bladder masses in children are extremely rare pathologic lesions. The presentation can include gross hematuria, irritable or obstructive voiding symptoms, and urinary infection. We present 2 cases in which large bladder masses suspicious for malignancy were diagnosed as benign lesions. One patient presented with abdominal pain and frequency 2 weeks after a minor bicycle accident and had a bladder wall abscess with sterile urine. Another child presented with gross hematuria and was found to have a giant cystitis glandularis lesion with no precipitating event or infection. The evaluation and differential diagnosis are discussed, and a review of the literature is presented.
