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

Abstract

Patient: Female, 14Final Diagnosis: Ovarian mucinous cystadenomaSymptoms: Abdominal enlargement • abdominal pain • constipationMedication: —Clinical Procedure: —Specialty: Obstetrics and GynecologyObjective:Rare diseaseBackground: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.

A 27-kg mucinous cystadenoma of the ovary presenting with deep vein thrombosis

“…MCAs mainly occur during middle age, as in our case, and they are rare among adolescents. There was, however, a report of an ovarian MCA in a premenarchal girl ( 6 ) . MCAs are usually unilateral, and are bilateral in 10% of cases (as in our case) ( 1 , 7 ) .…”

“…Giant ovarian cystadenomas are rarely observed today because of improved imaging techniques(5). Further, most ovarian cyst adenomas are epithelial cystadenomas, of which 25% are mucinous ( 6 ) . MCAs mainly occur during middle age, as in our case, and they are rare among adolescents.…”

“…In our case, PET-CT scan was performed because of a suspicion of malignancy. Although tumor markers can identify cyst characterization in most instances, they are more important in monitoring postoperative relapse ( 6 ) .…”

Epithelial ovarian tumors in a premenarchal girl: a rare case report

“…Ovarian tumors are relatively uncommon in paediatric age group and accounts approximately less than 2% of all childhood tumors and 6% of ovarian tumors in all ages [ 1 ]. In the premenarchal stage, the ovarian mass range from nonneoplastic lesion such as benign functional cysts to malignant tumors mostly germ cell in origin [ 1 2 ]. The ovarian tumors commonly seen in the second decade of childhood usually present with nonspecific clinical signs and symptom [ 1 2 ].…”

Therefore, it is difficult to make correct diagnosis preoperatively [ 1 2 ].…”
