ABSTRACT = {<b>Purpose:</b> A case of the rare, benign, Wilms’ tumor (WT) variant, metanephric adenofibroma (MAF), is presented.<br/>

<b>Materials and methods:</b> The patient is a 21-year-old female with an incidentally discovered enhancing renal mass. The diagnosis, workup and treatment are outlined.<br/>

<b>Results:</b> The 19 cm renal mass was ultimately resected via robot-assisted partial nephrectomy. Pathologic diagnosis at our institution was confirmed as a MAF by the National Wilms’ Tumor Study Group (NWTSG).<br/>

<b>Conclusion:</b> Difficult to differentiate from WT, it is imperative that MAF be recognized and appropriately diagnosed because unlike adult WT, the natural history of MAF is indolent and adjuvant chemo/radiation therapy is rarely necessary. This case reinforces the importance of review of potential WT variants by the NWTSG.},
