Giant mucinous cystadenoma of the ovary associated with disseminated peritoneal adenomucinosis

Abstract

Introduction: Mucinous cystadenoma is a multilocular tumor that secretes mucin in the epithelium, is most often formed in the ovary, but can also be located in the pancreas, appendix and very rarely in the urinary bladder or retroperitoneal level. Mucinous neoplasms are mostly benign tumors, however in smaller percentages they may be borderline or potentially malignant.

Objectives: This research aims to report a clinical case of giant ovarian mucinous cystoadenoma associated with disseminated peritoneal adenomucinosis.

Materials and Methods: A descriptive, retrospective study was performed to describe a clinical case of giant ovarian mucinous cystoadenoma associated
with disseminated peritoneal adenomucinosis. Obtained informed consent from the patient and authorization from the Teaching and Research Department, for the review of clinical records and access to images, for the publication of the present case.Clinical case:A 70-year-old female patient who presented a clinical picture of 1 year of evolution characterized by pelvic pain, progressive increase in the abdominal perimeter and abnormal uterine bleeding. To the physical examination in abdomen: presents a large mass that occupies all quadrants of the abdomen and that causes compression and breathing difficulty. as a surgical finding: giant tumor of ovary was found measuring 32x24 x15 cm, weighing approximately 20,000 grams. According to a pathological report,
it was a low-grade mucinous cystoadenoma associated with disseminated peritoneal adenomucinosis, which provides a better prognosis.

Results: As a benign neoplasm, satisfactory results were obtained. Patient with a good prognosis who is currently in stable clinical conditions, with follow-up at regular checkups.

Conclusion: Mucinous cystadenoma is a neoplasm that can originate in the ovary and that can grow much more than other annex masses, Behaving as benign but also recognized as precursors of ovarian cancer and can slowly transform into bordering tumors and evolve into invasive ovarian cancer, so prompt and accurate treatment is vital.
