Abstract:
Objective:To investigate the clinical, imaging, and pathological characteristics of renal oncocytoma, and to improve the understanding, diagnosis, and treatment of renal oncocytoma.Methods:The imaging and pathological data of two patients misdiagnosed with renal cell carcinoma in the 970 Hospital of PLA Joint Logistics Support Force from January to March 2021 were retrospectively analyzed. The relevant literature was reviewed and discussed.Results:The tumors were located in the left kidney of two patients, with diameters of 2.7 cm and 3.2 cm respectively. The patients underwent retroperitoneal laparoscopic removal of partial left kidney and retroperitoneal laparoscopic removal of the whole left kidney separately. The pathological results confirmed the diagnosis of renal oncocytoma.Conclusion:Renal oncocytoma is a rare benign renal cell tumor which is difficult to be diagnosed before surgery. Contrast-enhanced CT can provide evidence for the identification of renal oncocytoma. Its final diagnosis depends on pathological results.
