Huge mucinous ovarian borderline tumor: a case report

We present a case report of an atypical 9 kg intestinal like borderline mucinous ovarian cancer in a 58-year-old postmenopausal woman presenting with ascites, increased abdominal circumference, weight loss, and asthenia. A computed tomography scan revealed a 240 × 180 × 235 mm multilobulated abdominal mass associated with left pleural effusion and atelectasis. A 9 kg mass was resected by laparotomy with combined hysterectomy salpingo-oophoprectomy and appendectomy and multiple biopsies were taken from the omentum, surrounding tissues, and peritoneal walls. The patient was discharged with a wait and see follow up plan. Borderline ovarian tumors are a rare entity of malignancies, they usually occur in younger patients, are asymptomatic without high levels of tumor markers (CA19.9 > 10 000). Extensive surgical resection is still debated as most of these tumors occur in child-bearing age women. With the increasing number of atypical presentations, there is a greater need to generate evidence-based guidelines to guide the management of this disease.
