Abstract
A 71-year-old woman with suspected endometrial cancer underwent robotic-assisted hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymph node dissection, and infracolic omentectomy revealing a stage II uterine carcinosarcoma with components of serous adenocarcinoma and undifferentiated spindle cell sarcoma. There was no evidence of distant metastasis at the time of surgery. However pelvic washings were positive for malignant cells. She received adjuvant chemotherapy and vaginal cuff brachytherapy. Forty months later she developed a subcutaneous mass at the location of previous port site which was confirmed to be recurrence of the uterine primary. She subsequently developed additional distant metastases to the abdominal wall, lungs, and bone. Port site metastasis (PSM) was the earliest indicator of disseminated metastatic disease in this patient. We review challenges in the management of patients with PSM and propose that PSM be considered as a sign of systemic disease even when presenting as an apparently isolated recurrence.
