[Evaluation of atypical ductal hyperplasia]

The author introduced and explained the criteria of Page et al. on the evaluation of atypical ductal hyperplasia (ADH), and also demonstrated various figures of ADH which seemed to be representative in our file following the criteria. Professor Page, who attended this panel discussion, agreed most of these figures were ADH. The author wishes to evaluate ADH after the criteria of Page et al. so as to be more generalized and standardized in Japan.
