Giant mature teratomas (>20 cm in diameters) sometimes may contain malignant immature elements or tissues. These small foci of immature tissues could be missed at frozen section resulting inadequate initial surgical intervention. There is no large series in the literature either showing the accuracy of frozen section on huge ovarian teratomas or concerning the adequate surgical approach at the ...
