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.
