Renal Oncocytoma: Clinical and Therapeutic Aspects about a Case Series and Literature Review

Abstract

Introduction: The gold of this work was to study the clinical and therapeutic management aspects of renal oncocytoma in our settings. Our Observations: Case 1: there was a 44-year-old patient being followed up for a urinary tract infection due to Escherichia coli. The urological CT-scan showed a tumor-like process on a horseshoe kidney. Radical nephrectomy was performed and the histology report confirmed renal oncocytoma; Case 2: it involved a 62-year-old hypertensive patient. Clinical examination revealed a grade II cystocele and medical imaging showed a tumor-like mass at the lower pole of the right kidney. Radical nephrectomy was performed and histology was concluded in favor of renal oncocytoma; Case 3: there was a 64-year-old patient monitored for chronic renal failure and on dialysis for 6 months. Imaging showed a heterogeneous mass developing from the kidney. Histology and immunohistochemistry confirmed renal oncocytoma. Conclusion: Imaging could contribute greatly to preoperative diagnosis. However, there is a need to think about renal oncocytoma when evaluating kidney tissue masses.
