title: A case of mixed-type dysgerminoma with a high serum concentration of both human chorionic gonadotropin and alpha-fetoprotein in a child.
abstract: Dysgerminoma is divided into two types: pure and mixed. The mixed type is related to other various elements of germ cell tumors. We experienced a case of mixed type dysgerminoma with a high serum concentration of both human chorionic gonadotropin and alpha-fetoprotein. The patient was a 6 year old girl who was admitted to the Hamamatsu University School of Medicine with an abdominal mass. Laboratory investigations revealed elevated serum alpha-fetoprotein and high concentration of serum beta-human chorionic gonadotropin. The tumor originated from the left ovary. The histopathological diagnosis was dysgerminoma. Serum human chorionic gonadotropin and alpha-fetoprotein levels were useful markers in monitoring the response to treatment in this patient.
