Abstract excerpt

CONTEXT.—: In 2019, papillary renal neoplasm with reverse polarity (PRNRP) was defined as a new neoplasm because it has a predominately tubulopapillary pattern lined by a single layer of cuboidal and eosinophilic cells with apically located round nuclei. Immunohistochemically, this neoplasm showed expression of GATA-3 and L1CAM and had recurrent KRAS mutations. OBJECTIVE.—: To estimate the incidence of PRNRP and...
