A healthy 51-year-old woman presented with increasing abdominal and pelvic pain. Computed tomography imaging of the abdomen and pelvis showed an 11.6-cm pelvic mass, retroperitoneal lymphadenopathy, right hydronephrosis, and mesenteric tumor deposits ( Fig 1A ). A serum CA-125 was elevated at 1,149 U/mL. She underwent primary surgical cytoreduction including hysterectomy, bilateral salpingo-oophorectomy, appendectomy, resection of pelvic tumor, omentectomy, and low anterior resection with colorectal anastomosis. Intraoperatively, she was noted to have bilateral ovarian masses, pelvic and para-aortic lymphadenopathy, and a 4-cm omental tumor; in addition, both the uterus and rectosigmoid colon had adherent tumor deposits. All gross tumor was resected during the procedure. Final pathology confirmed high-grade serous carcinoma of ovarian origin ( Fig 1B ) that was determined to be stage IIIC as a result of upper abdominal involvement with greater than 2-cm tumor deposits, as well as retroperitoneal lymph node involvement. She underwent germline genetic testing, which did not identify a mutation in the , , , , or genes. She presented for adjuvant chemotherapy after an optimal (R0) resection.
