The diagnostic criteria are: (1) dense glands, Accounting for more than the stroma (gland / stroma> 1); (2) cytological changes of the glandular epithelial cell nucleus and / or cytoplasm of the structurally abnormal gland are different from epithelial cells of the normal background gland; (3) The maximum linear length is more than 1 mm.
