OBJECTIVE: Two cases of metanephricadenoma are presented, a rare benign renal tumor,and a literature review is done under the current WHOclassification (2016).METHODS: Standard histopathological study wasperformed with hematoxylin-eosin and immunohistochemistryto analyze the expression of WT, Vimentin, Racemase,CK7, CD10 and RCC.RESULTS: Neoplasms of 3 and 4.5 cm, histologically,exhibiting tubulopapillary architecture. There was noevidence of significant nuclear atypia and mitoticfigures. Immunohistochemical study showed positiveimmunoreaction for WT1 and Vimentin in tumor cells.CONCLUSIONS: Two new cases of metanephricadenoma are presented and a review of the literaturewas performed in order to discuss the prognosis anddifferential diagnosis of metanephric adenoma.
