Metanephric adenoma in a solitary kidney.

Abstract

A case of metanephric adenoma occurring in a solitary kidney of a 31-year-old man is presented. Metanephric adenoma is extremely rare and its diagnosis should be considered in a patient with a well circumscribed renal tumour and concomitant paraneoplastic syndromes. Radiological features of the tumour are non-specific and histopathological examination is essential to establish a definitive diagnosis. Recognition of the tumour is of potential importance as conservative treatment with complete surgical enucleation will suffice in all cases.
