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.</dc:description><dc:publisher>INT SCIENTIFIC LITERATURE, INC</dc:publisher><dc:date>2014</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/16035</dc:identifier><dc:identifier>https://doi.org/10.12659/ajcr.890862</dc:identifier><dc:identifier>1941-5923</dc:identifier><dc:language>en</dc:language><dc:relation>AMERICAN JOURNAL OF CASE REPORTS</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/16035</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
