Gonadoblastoma occurring in a 6-year-old phenotypically girl, the 19th case in the Japanese literatures, is reported. She was admitted because of lower abdominal painful mass. On physical and radiological examinations the findings suggested twisted ovarian tumor. In laparotomy fist-sized, well-capsulated tumor of the left ovary with torsion of pedicle was found, and the left salpingoophorectomy was carried out. Chromosomal karyotype was 46, XY. Histologically, the specimen demonstrated gonadoblastoma with dysgerminoma. The other gonadoblastoma was identified through the right salpingoophorectomy three months later. Karyotype shoud be examined in female with primary amenorrhea or virilism such as hirsutism or clitoromegaly. If she has Y-chromosome, exploratory laparotomy should be indicated. Early bilateral gonadectomy is necessary for those with gonadoblastoma because of malignancy highly combined.
