Abstract
Pediatric extrarenal malignant rhabdoid tumors (MRTs) are rare, aggressive tumors with a poor prognosis (20% 5-year survival). There are currently fewer than 10 published case reports of primary MRT of the bladder. We report the case of an 18-month-old female with an isolated MRT of the bladder which was initially misdiagnosed as an inflammatory myofibroblastic tumor on biopsy. We review the history, tumor biology, histology, and current management of extrarenal MRT, along with lessons learned from the difficulty with the patient's initial diagnosis.
