The simultaneous presentations of endometrial and ovarian carcinomas are well-recognized. Oncocytoma is a benign renal tumor. In this presentation, it was purposed that the simultaneous presentations of endometrial, ovarian and renal tumors are reviewed. A 48-year-old woman presented with abdominal distention was found to have stage IB endometrioid cell carcinoma of the ovary, stage IC endometrial carcinoma of endometrioid type, and oncocytoma of the right kidney. Radical hysterectomy, bilateral salpingooopherectomy, retroperitoneal lymph node dissection, and right nephrectomy were performed. The present case is the first case of simultaneous presentation of renal oncocytoma, endometrioid type endometrial and ovarian carcinomas.
