Metastatic serous endometrial carcinoma to the ureter

摘要

Metastatic endometrial carcinoma involving the renal parenchyma has been reported. However, ureteral metastasis is exceedingly rare. Here we describe what we believe to be the first case report of metastatic endometrial serous carcinoma to the ureteral and renal pelvic urothelium. The patient is a 68 year old female diagnosed with endometrial serous carcinoma three years prior to presentation who was found to have metastatic disease within the right ureter and retroperitoneal lymph nodes. Following a complete response in the lymph nodes to chemotherapy, she was treated with robot-assisted right nephroureterectomy for residual, isolated PET-avid right ureteral metastasis.
