[Ipsilateral metanephric adenoma and clear-cell carcinoma. Personal experience and review of the literature].
OBJECTIVE
To perform an update in such an infrequent pathology and to report our own experience.


METHODS
We report two new cases and review the national and international literature.


RESULTS
We report two cases of ipsilateral metanephric adenoma and clear cell carcinoma. The first case, metachronous, was detected after 15 months of follow-up in a patient who underwent partial nephrectomy due to clear cell carcinoma. The second one, synchronic, was incidentally discovered in the surgical specimen.


CONCLUSIONS
Metanephric adenoma is as infrequent neoplasia; its diagnosis is histological, being difficult to suspect by complementary diagnostic tests, so that most cases undergo surgical treatment in spite of its benign character.
