Trisomy 12 and translocation (7;9) in an ovarian immature teratoma.

We report a case of an immature malignant ovarian teratoma with peritoneal implants diagnosed in an 18-year-old woman.

A stem cell line has been obtained with cell culture, having a germ cell character and a yolk sac configuration. This line possessed a trisomy 12 and a translocation (7;9) similar to other chromosomal abnormalities describe…
