MICROGLANDULAR ADENOSIS Figure 6-16 MICROGLANDULAR ADENOSIS A: In this case of microglandular adenosis, the cells have clear cytoplasm. The small round glands are haphazardly distributed in the stroma. B,C: Intermediate (B) and high (C) power illustrate the bland features of microglandular More about this image found in MICROGLANDULAR ADENOSIS A: In this case of microglandular adenosis, the ce...

MICROGLANDULAR ADENOSIS Figure 6-21 MICROGLANDULAR ADENOSIS A: On core needle biopsy, microglandular adenosis may be misinterpreted as a low-grade invasive ductal carcinoma. B: The growth pattern and lack of myoepithelial cells do not differentiate one diagnosis over the other. The eosinophilic More about this image found in MICROGLANDULAR ADENOSIS A: On core needle biopsy, microglandular adenosis ...

ATYPICAL MICROGLANDULAR ADENOSIS Figure 6-19 ATYPICAL MICROGLANDULAR ADENOSIS A: The nests in this case of atypical microglandular adenosis are composed of cells with clear cytoplasm and variably sized nuclei. B: At higher power, the nuclear atypia is better seen. Note the abundant apoptotic More about this image found in ATYPICAL MICROGLANDULAR ADENOSIS A: The nests in this case of atypical mic...

METAPLASTIC CARCINOMA ARISING IN MICROGLANDULAR ADENOSIS Figure 6-20 METAPLASTIC CARCINOMA ARISING IN MICROGLANDULAR ADENOSIS A: At low power, there are small glands containing secretions distributed across the central portion of the field. A cellular proliferation can be appreciated More about this image found in METAPLASTIC CARCINOMA ARISING IN MICROGLANDULAR ADENOSIS A: At low power, ...

MICROGLANDULAR ADENOSIS Figure 6-17 MICROGLANDULAR ADENOSIS A few small glands with eosinophilic secretions in the adipose tissue of the breast may be overlooked due to the lack of any stromal reaction.

ATYPICAL MICROGLANDULAR ADENOSIS Figure 6-18 ATYPICAL MICROGLANDULAR ADENOSIS A: Some of the glands have filled in and become larger nests. In addition, there are enlarged nuclei with prominent nucleoli. B: In another area of the same case, there is a more pronounced nested pattern and moderate More about this image found in ATYPICAL MICROGLANDULAR ADENOSIS A: Some of the glands have filled in and ...

MICROGLANDULAR ADENOSIS Figure 6-15 MICROGLANDULAR ADENOSIS A: At low power, small round glands are seen to be infiltrating through the breast parenchyma in a random pattern. B: Eosinophilic secretions are seen in many of the glands. The cytoplasm is somewhat amphophilic. C: At high power More about this image found in MICROGLANDULAR ADENOSIS A: At low power, small round glands are seen to be...

SECRETORY ADENOSIS Figure 6-25 SECRETORY ADENOSIS A: Scanning magnification view of a case of secretory adenosis shows the haphazard arrangement of small glands. B: High power shows the simple round glands with luminal secretions resembling microglandular adenosis. C: A p63 stain confirms More about this image found in SECRETORY ADENOSIS A: Scanning magnification view of a case of secretory a...
