Extract
Sir,
Renal oncocytoma accounts for approximately 5% of renal parenchymal tumours [1], but bilateral, multifocal renal oncocytoma is rare. In recent years renal oncocytoma has been more frequently identified. Possible explanations include more frequent screening in patients with non-specific symptoms causing a spurious increase in incidence [2]. Renal oncocytoma represents a highly differentiated eosinophilic granular cell renal parenchymal tumour. It is non-aggressive and has a favourable prognosis [3]. There are sporadic reports on bilateral, multifocal oncocytomas having semi-malignant potential, i.e. locally invasive growth, and reports on renal oncocytoma plus renal cell carcinoma as simultaneous, but separate, lesions [4,5]. Usually these patients are managed by enucleation of the large tumours. Overall prognosis is regarded as acceptable, considering the generally benign nature of these neoplasms [6]. We report a patient with bilateral, multifocal renal oncocytomatosis, who had rapidly progressive renal failure. Bilateral nephrectomy was performed to prevent a potential extrarenal progression.
