A 9-kg Ovarian Mucinous Cystadenoma in a 14-Year-Old Premenarchal Girl

Patient: Female, 14 Final Diagnosis: Ovarian mucinous cystadenoma Symptoms: Abdominal enlargement • abdominal pain • constipation Medication: — Clinical Procedure: — Specialty: Obstetrics and Gynecology OBJECTIVE: Rare disease BACKGROUND: Although ovarian tumors are most commonly observed in adults, they relatively rarely occur in children. The majority of ovarian masses encountered in the premenarchal or childhood stages are non-neoplastic lesions such as benign functional cysts. Epithelial tumors account for 8–10% of all ovarian tumors and are histologically classified as mucinous or serous. The most common benign epithelial ovarian tumor is cystadenoma. CASE REPORT: We report the case of a 14-year-old premenarchal girl with chronic abdominal pain, constipation, and abdominal enlargement. A computed tomography detected a huge left ovarian cystic tumor. A 9-kg ovarian tumor was removed surgically. Pathology showed a benign mucinous cystadenoma (MCA). CONCLUSIONS: Ovarian neoplasms in children present a diagnostic quandary, and very often the diagnoses are missed or delayed. When the diagnosis is made, a prompt and fertility-preserving surgical treatment must be performed and followed to prevent recurrence.
