i(12p) in a malignant ovarian tumor.
We have found one or more copies of i(12p) in an ovarian germ cell tumor, histologically a yolk sac tumor. This chromosome marker is characteristically associated with germ cell tumors in males. This report indicates that further investigation is necessary to establish the role of the i(12p) marker in the pathogenesis of germ cell tumors also in females.
