Mucinous cystadenomas are rare ovarian tumors in premenarchal girls, yet they may present as rapidly enlarging, large abdominal masses that generate obstructive symptoms. Early identification and timely surgical management are emphasized to reduce the risk of complications, often involving salpingo-oophorectomy. The report highlights the need for heightened awareness among pediatric healthcare providers to support accurate diagnosis and appropriate treatment planning.

Mucinous cystadenomas are rare ovarian tumors in premenarchal girls but can present as rapidly growing large abdominal masses causing obstructive symptoms. Early recognition and timely surgical intervention, often requiring salpingo-oophorectomy, are crucial to prevent complications. Awareness among pediatric healthcare providers is essential for accurate diagnosis and management. | | | --- | --- | | 1 | Introduction | ovary-conserving techniques in the surgical management of benign adnexal disease [5] . | | Tumors of the ovaries can be categorized as epithelial (cystadenoma, borderline cystadenoma, and cystadenocarcinoma), stro- | Hemorrhage, torsion, and rupture are the most frequent compli- | | mal (granulosa-theca, Sertoli, and Leydig cells), and germ cell (undifferentiated and extraembryonic) [1] . | cations of benign ovarian cysts [4] . | | Mucinous Cystadenomas (MCAs) make up 10%–15% of all ovarian tumors [2] . | 2 | Case Report | | | A 13-year-old female was brought to the emergency depart- | | MCAs are tumors that are lined by mucin-producing epithelial | ment complaining of rapidly progressive abdominal enlarge- | | cells.
