A 54-year-old woman referred to a specialist unit for weight loss, lethargy, and a palpable pelvic mass. Thought to have ovarian cancer metastasized to the kidney, underwent a left nephrectomy and para-aortic clearance, with a total abdominal hysterectomy and bilateral salpingo-oophorectomy with peritoneal biopsies. Histology proved it was actually a renal cell carcinoma metastasized to the ovaries. During further follow ups she had developed bone and pulmonary metastasis and died shortly after the diagnosis of metastasis. With only 14 reported cases in the literature increased awareness would aid management of similar cases.
