ENO2 and mesenchymal cell neoplasm: Negative staining for these three markers (FGF23-, SSTR2A-, and NSE-) could be used to rule out phosphaturic mesenchymal tumors.[20–22] Compared with PMTMCTs, some PMTMECT tumor cell nests were positive for AE1/AE3 and negative for vimentin, indicating an epithelial component presence.
