Abstract:
A 13-year-old boy presented with a well limited, juxta-hilar intrarenal mass. Needle biopsy suggested a nephrogenic nephroma. The child underwent tumorectomy. The tumor was composed of uniform metanephric tubules with small calcospherites. This rare entity is known for benign course. Half of its cases have been described in children, the other half in adults, mainly women in their fifties.
