Objectives: Metanephric adenoma is arelatively unfrequent asymptomatic embryogenic renal tumor which is generally diagnosed by an abdominal diagnostic tests indicated for other reasons. Differential diagnosis with benign and malignant tumors has to be performed. Methods/Results: We report one case of metanephric adenoma with intense necrotic-hemorrhagic and cystic changes with a size not previously referred in the literature. Conclusions: Cystic and hemorrhagic changes inbenign renal tumors make differential diagnosis with malignant tumors mandatory. Surgery is necessary in almost all cases and histologic study will give the diagnosis.
