Definition

Metanephric neoplasms comprise a spectrum of kidney tumors containing renal epithelial or stromal cells or both.

Summary

Metanephric tumorsGenetic event(s)
Metanephric adenoma BRAF V6000E mutation in 80% of the cases 1. Variant BRAF mutations were also reported 2. Genetic evidence for potential malignant evolution by acquiring pathogenic alterations in addition to BRAF, TERT promotor mutation, CDNK2A loss, MYC amp 3.
t(9;15)(p24;q24)/KANK1::NTRK3, lacking BRAF mutation mainly in young patients 4,5,6. Recurrent gain of chromosome 19 by array CGH 7.
Metanephric adenofibroma BRAF V6000E mutation in isolated cases 8.
Metanephric stromal tumor Predominantly affecting children, BRAF V600E mutations in most of the cases 8
