Mitotic activity of schwannomas.
A significant (p less than 0.01) difference in the mitotic index between 31 benign and 4 malignant schwannomas is reported. An increased mitotic activity has been related to malignancy in previous works, although no statistical studies have been carried out on its diagnostic value. Our results suggest that the mitotic index should be considered an effective, convenient feature of distinction in doubtful instances, especially as no other trait of malignancy can be similarly measured.
