Background:
Ovarian tumors are rare in the pediatric age group and thus diagnostic and treatment strategies are heterogeneous. This study aims to evaluate ovarian tumors with a focus on age at presentation, imaging characteristics, diagnostic strategy, tumor presentation and management.
Methods:
Data was collected retrospectively from patients admitted between 1991 and 2008 for the evaluation and therapy of ovarian tumors.
Results:
Twenty-five patients were identified with neoplastic ovarian lesions (mean age 10.7 years). Sixteen patients (64%) underwent surgery for benign and 9 (36%) for malignant tumors. Benign tumors (n=16) had a mean diameter of 10.7 cm and mean age at presentation was 9.6 years compared to a diameter of 18.6 cm and 12.3 years in the malignant group (n=9). Elevated tumor markers were observed in 3 (12.5%) benign tumors and in 7 (77.8%) malignant tumors. In preoperative ultrasound investigation, cyst formation was identified in 4 benign tumors and solid tumor mass in 2 malignant tumors. A minimally invasive surgical approach was chosen in two patients, while open surgery was opted for in the rest.
Conclusion:
Cyst formation, small tumor size and younger age at presentation were characteristic of benign tumors. Malignant tumors often presented with elevated tumor markers, a larger size and a solid consistency. Diagnostic dilemmas remain for both tumor groups due to the different tumor types and the heterogeneity of presentation.
