Abstract
Mucinous ovarian cystadenoma is a benign tumor, which accounts for 15% of all ovarian tumors and when diagnosed, 80% are benign, 10% limitrophe, and 10% malignant. It is a cyst that arises from the ovary surface epithelium, presenting multilocular features with a plain surface. It is more common between 30- and 50-years old persons and clinical signs differ from other ovarian pathologies because they present rapid growth, reach large dimensions, and evolve with peritoneal pseudomyxoma, causing a significant increase in abdominal volume. Imaging methods such as ultrasonography and computed tomography, as well as the tumor markers CA-125 and CEA, are fundamental for its elucidation and therapeutic planning. We report a case of giant mucinous cystadenoma of the left ovary in a 61-year-old patient admitted to the emergency room.

The present paper describes the case of a giant left mucinous ovarian cystadenoma
Mucinous ovarian cystadenoma is a benign tumor, which originates from the epithelium of the ovarian surface, with the possibility of reaching large dimensions. 15% of all ovarian masses are made up of them, 80% of the mucinous tumors are benign
Summary
Many are the histological types of ovarian neoplasms and their classification is described as benign, limitrophe and malignant. Giant ovarian cysts are somewhat uncommon, but in developing countries it is a well-established pathology They are considered giants when they are larger than 15 cm or occupy the entire peritoneal cavity [4,5]. Computed tomography of the entire abdomen was performed, demonstrating extensive tumor lesion and cystic hypodense occupying a large part of the abdominal cavity (Figure 1). Immunological examination of tumor markers found CA-125: 116.0 U/ml (reference: less than 35 U/ml) and CEA: 1.30 ng/ml (reference: non-smokers: 3.8 to 5, 0 ng/ml, smokers: 5.5 to 6.5 ng/ml) Laboratory tests such as hemogram, coagulogram, urea, creatinine and liver enzymes were requested, but without any changes. After one month, the patient was asymptomatic
