Slide 90. In this slice a duct (D) is noted. Multiple coarse lobules are studding the duct. When the duct tree shows many foci close together of ductal hyperplasias there seems to be a "field effect" for these lesions to become cancerous. Photographed at 6.3x magnification

Slide 91. A single focus of 5-8 coarse ductules appears in this image. One ductule is outlined by 3 arrows. Photographed at 6.3x magnification

Slide 92. In the corresponding histologic slide an arrow points to the coarse ductule outlined in the slice. Photographed at 25x magnification

Slide 93 At higher magnification, irregular spaces are seen surrounded by pleomorphic "streaming" of the cells. This is DUCTAL HYPERPLASIA, FLORID (DHF). It is considered a benign hyperplasia even though it has a necrotic center. Photographed at 63x magnification
