Vaginal Rhabdoid Tumor Presenting as Prenatal Lower Urinary Tract Obstruction and Vaginal Mass.

Extracranial malignant rhabdoid tumors (MRT) are very rare and aggressive tumors. They are typically associated with an extremely poor prognosis, particularly when seen in the infant and neonatal population. Here we present the case of a newborn female born with a large vaginal mass and evidence of prenatal lower urinary tract obstruction (LUTO) that was determined to be a MRT of vaginal origin. In this report, we will also discuss an overview of extracranial MRT tumor biology and treatment considerations.
