Oncocytoma in a horseshoe kidney

Area of Science:

• Urology
• Nephrology
• Oncology

Background:

• Renal oncocytoma is a benign kidney tumor with increasing reported incidence.
• Horseshoe kidneys represent a common congenital anomaly with potential surgical complexities.

Observation:

• A rare case of renal oncocytoma was identified in a patient with a horseshoe kidney.
• The tumor's location within the fused lower poles of the horseshoe kidney presented unique diagnostic and surgical considerations.

Findings:

• This report details the characteristics and management of renal oncocytoma in the context of a horseshoe kidney.
• The discussion includes the rarity of oncocytoma and the specific challenges associated with tumors in horseshoe kidneys.

Implications:

• This case contributes to the understanding of renal oncocytoma in complex renal anatomies.
• It underscores the importance of considering anatomical variations when diagnosing and treating kidney tumors.
