    AMKL associated with mediastinal germ cell tumors typically occurs in younger adults, i.e. ages 13–36 (average age 24). [1] Cases occurring in children aged ≤18 years, which represent ~20% of all cases, could be regarded in the non-DS-AMKL category. [20] Cases of the disease not associated with mediastinal germ cell tumors occur in adults ...

    Dysgerminoma is the most common type of malignant germ-cell ovarian cancer. Dysgerminoma usually occurs in adolescence and early adult life; about 5% occur in prepubertal children. Dysgerminoma is extremely rare after age 50. It occurs in both ovaries in 10% of patients and, in a further 10%, a microscopic tumor is in the other ovary. [citation ...
