Metastatic urachal carcinoma of the ovary.

A 52-year-old woman had undergone a partial cystectomy for a cystic mass at the dome of the urinary bladder in 1997. The pathological diagnosis was a urachal mucinous cystadenoma with borderline malignancy. Twelve years later, multiple masses were noted on the uterus, ovaries and abdominal wall. She underwent debulking surgery, including a total hysterectomy, bilateral salpingo-oophorectomy, pelvic lymph node dissection, infracolic omentectomy, appendectomy, colon mass removal and abdominal wall mass removal. Remnants of the tumor were seeded throughout the abdominal cavity. The pathological evaluation confirmed metastatic urachal mucinous adenocarcinoma in both ovaries, the abdominal wall, the colon mass, the uterosacral ligament and the bladder. Adjuvant chemotherapy with paclitaxel and carboplatin was administered, which showed stable disease. She is now undergoing second-line chemotherapy.
