Gross Hematuria in an Adolescent Secondary to a Rare Bladder Tumor: A Case Report and Review of Inflammatory Myofibroblastic Tumors of the Urinary Bladder

Inflammatory myofibroblastic tumor (IMT) is a tumor of unknown neoplastic potential that rarely arises in the genitourinary tract. We present the case of an otherwise healthy 16-year old boy with gross hematuria who underwent cystoscopy and transurethral resection of the bladder tumor without complication. Biopsy and immunohistochemistry were consistent with anaplastic lymphoma kinase-positive IMT. In addition to presenting this case of IMT, we review presentations, management and prognosis of bladder IMT.
