Oophorectomy performed in children is extremely uncommon. We aimed to investigate the disease pattern and the association between the underlying pathology and the clinical presentation among those patients who had their ovaries removed in their childhood. A retrospective study was performed on 41 consecutive children who underwent oophorectomy in a tertiary referral centre in the period between June 1995 and May 2008. The median age was 11 years, ranged from 11 weeks to 15 years at the time of surgery. The primary presentations were acute lower abdominal pain (n= 20), progressive abdominal distension or abdominal mass (n= 13), chronic abdominal pain (n= 3), irregular menses (n= 1), antenatal diagnosis (n= 3) and incidental finding (n= 1). Ultrasound examination was performed in 31 patients and positive findings of ovarian pathology were found in all but one examination. Twenty cases of ovarian torsion were confirmed intra-operatively. Patients presenting with acute abdominal pain were more likely to have torsion than other presentations (P < 0.01). Non-neoplastic conditions and ovarian neoplasms were found in 11 and 30 patients, respectively. The most common neoplasm was mature teratoma (52%). Malignant neoplasms included immature teratoma (n= 3), dysgerminoma (n= 1), mixed dysgerminoma + yolk sac tumour (n= 2), yolk sac tumour (n= 2) and juvenile granulose cell tumour (n= 1). Malignant neoplasms were found to have more chronic presentation and less torsion than benign pathologies (P < 0.05). Although ovarian pathology is uncommon in children, a girl presenting with acute lower abdominal pain or progressive abdominal distension should raise the suspicion and prompt immediate investigation to rule out ovarian torsion or ovarian neoplasms.
