Successful Management of a Giant Mucinous Cystadenocarcinoma of the Ovary Through Laparotomy: A Case Report.

Giant mucinous cystadenocarcinoma of the ovary is rarely described. Huge ovarian masses are mostly benign, but malignancy should be ruled out by investigations and clinical assessment. Here, we present a case of a large mucinous cystadenocarcinoma of the ovary in a 48-year-old postmenopausal woman. Imaging examinations revealed a large cystic tumor that filled the whole abdominal cavity. Despite the difficulties presented by the size of the tumor and its malignant potential, laparotomy was carried out, which included bilateral salpingo-oophorectomy, total abdominal hysterectomy, exploration of other intra-abdominal organs, and pelvic lymphadenectomy. Histopathology indicated the presence of mucinous cystadenocarcinomas. Adjuvant chemotherapy was given post-operatively, and the patient maintained remission during follow-up. This case emphasizes the need for early detection by simple imaging modalities such as ultrasonography in cases of ovarian masses. Most adnexal masses, if detected early, are amenable to surgical management with a good prognosis. Large masses underline the need for a multidisciplinary approach to improve patient outcomes.
