Median age at presentation was 13.0 years (range 0.9–15.7), similar in both the 33 (73%) girls with a benign tumor and the 12 (27%) girls with a malignant tumor. The tumors with the highest propensity to metastasize (yolk sac tumors, mixed germ cell tumors, small cell carcinoma) were only found in girls > 9 years. Elevated serum alpha‐fetoprotein and CA 125 values associated more often with malignant tumors (<italic>p </italic>< 0.001 and <italic>p </italic>< 0.031, respectively). There were no deaths or local recurrences. Four girls with a mature teratoma developed a contralateral benign ovarian tumor during follow up.</p> </sec> <sec id="aogs12598-sec-0008" sec-type="section"> <title>Conclusions</title> <p>Both benign and malignant ovarian tumors are rare in the pediatric population, but the incidence increases with age. High alpha‐fetoprotein and CA 125 levels were associated with malignant tumors. The prognosis of the pediatric ovarian tumors seems to be favorable.</p> </sec> </abstract>
