<bold>FIG. 11.18.</bold> Ductogram performed for bloody nipple discharge. Multiple, irregular intraluminal filling defects are noted in the contrast-filled (white) ductal system (<italic>arrowheads</bold>). Extensive ductal carcinoma <italic>in situ</bold> was found at surgical biopsy.

<bold>FIG. 12.4.</bold> Solid masses. <bold>A:</bold> Invasive lobular carcinoma. This small solid mass (<italic>arrow</bold>) has indistinct margins, an irregular shape, a nonparallel orientation, and posterior shadowing, all features of malignancy. <bold>B:</bold> Mixed invasive ductal and lobular carcinoma. This larger mass has all of the features characterizing the smaller version in <bold>A.</bold> In addition, the infiltrative nature of the cancer is seen in spicules (<italic>arrows</bold>) extending into the surrounding f...

Mammogram of breast cancer (note the irregular shape and borders of the growth)
Carcinoma of the breast. Mammogram. An irregularly shaped, dense mass (arrows) is seen in this otherwise fatty breast.
<bold>FIG. 5.2.</bold> Nipple inversion from breast cancer.
<bold>FIG. 9.4.</bold> Atypical ductal hyperplasia. Near the center of this space is a proliferation of relatively uniform epithelial cells with monomorphic, round nuclei. However, this proliferation involves only a portion of the space. In other areas, the proliferating epithelial cells maintain their orientation to one another. Thus, this lesion has some of the features of low-grade ductal carcinoma <italic>in situ</bold> and is best categorized as atypical ductal hyperplasia.
