FIGURE 12-12 DCIS intermediate grade, apocrine type. Double spot compression magnification (1.8×) view. Punctate, round, and amorphous calcifications (arrows) of variable density demonstrate a linear orientation (segmental distribution). A few linear (casting) forms are present.

FIGURE 12-13 DCIS, intermediate to high nuclear grade. (A) Spot compression magnification (1.8×) view demonstrating a cluster of amorphous calcifications with low but variable density. Fibrocystic changes (e.g., hyperplasia, ADH, sclerosing adenosis, columnar alteration with prominent apical snouts and secretions), papilloma, and fibroadenoma are in the differential. (B) Specimen radiography with magnification (3.5×) highlights the punctate nature of amorphous calcifications seen mammographically. On a specimen, magnification can be increased so that amorphous calcifications are better “resolved” into tight clusters of punctate calcifications. On a patient, the amount of magnification that can be obtained is limited, and as such, tight clusters of punctate calcifications are not well defined and may appear “amorphous.”
