GIANT OVARIAN MUCINOUS CYSTADENOMA

Objectives. Mucinous ovarian tumors are a variant of epithelial neoplasms and constitute from 10% to 15% of the structure of primary ovarian neoplasms.

Case presentation. Giant mucinous ovarian tumors are a rather rare phenomenon and are presented in the specialized literature as sporadic observations. Given the rarity of giant mucinous ovarian tumors, we present our own clinical observation.

Patient C., 24 years old, was hospitalized for surgical treatment with detected giant volume formation for 5 months. It causes pain in the lower abdomen, the increase in volume of the abdomen. At admission the condition is relatively satisfactory. The abdomen increased in size due to a volume formation in the small pelvis that reaches the xiphoid process. In order to assess the volume of the surgical intervention, the stratification of the formation, a computed tomography was performed, where a massive cystic formation of an indeterminate, well-contoured, septate, polylobular configuration was detected at the Th12 - S5 level, possibly originating from the left ovary with homogeneous liquid content, native content density +10 HU, dimensions 24.8x18.3x12.6 cm without signs of infiltration of adjacent tissues, possible mucinous cystadenoma. The decision was made to perform surgery. During the revision of the abdominal cavity, a 20x20 cm multicameral volume formation was detected. An adnexectomy was performed. The patient was discharged on the 9th postoperative day.

Conclusions. Giant mucinous ovarian tumors are a rather rare pathology. In the surgical treatment of giant mucinous ovarian tumors, preference should be given to ovarian-preserving surgery in women of reproductive age.
