SCLEROSING ADENOSIS Figure 6-5 SCLEROSING ADENOSIS A: At low power, this example of sclerosing adenosis appears to be composed predominantly of cords of cells with scattered admixed glands. B: At higher power, both patterns are better appreciated. Myoepithelial cells are difficult to discern.

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 ...

TUBULAR ADENOSIS Figure 6-23 TUBULAR ADENOSIS A: On low power, tubular adenosis has the appearance of a haphazard arrangement of branching tubules. B: Intermediate power view reinforces this impression of an irregular, possibly infiltrative process. C: On high power, myoepithelial cells More about this image found in TUBULAR ADENOSIS A: On low power, tubular adenosis has the appearance of a...

NODULAR ADENOSIS Figure 6-8 NODULAR ADENOSIS A: At scanning magnification, a large, relatively circumscribed collection of small glands is apparent. B: Higher-power examination reveals the characteristic features of sclerosing adenosis. Mass-forming lesions such as this are referred More about this image found in NODULAR ADENOSIS A: At scanning magnification, a large, relatively circums...

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...

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...

LOBULAR CARCINOMA IN SITU IN ADENOSIS Figure 4-12 LOBULAR CARCINOMA IN SITU IN ADENOSIS A: This low-power image shows an area of adenosis expanded by a proliferation of monomorphic epithelial cells. B: At intermediate power, the cytologic dyshesion characteristic of LCIS is appreciated. C More about this image found in LOBULAR CARCINOMA IN SITU IN ADENOSIS A: This low-power image shows an are...

MYOEPITHELIAL CELL STAINS IN ADENOSIS Figure 6-11 MYOEPITHELIAL CELL STAINS IN ADENOSIS A: In this case of lobular carcinoma in situ (LCIS) involving adenosis, the arrangement of some of the epithelial cell nests suggests invasive carcinoma rather than LCIS in adenosis. B: A SMMHC stain More about this image found in MYOEPITHELIAL CELL STAINS IN ADENOSIS A: In this case of lobular carcinoma...

ATYPICAL APOCRINE ADENOSIS Figure 6-14 ATYPICAL APOCRINE ADENOSIS The cytologic features are those of apocrine metaplasia, but there is tremendous variability in the size and shape of the nuclei, warranting a diagnosis of atypical apocrine adenosis in this core needle biopsy specimen. More about this image found in ATYPICAL APOCRINE ADENOSIS The cytologic features are those of apocrine me...

“ADENOMYOEPITHELIOSIS” Figure 7-43 “ADENOMYOEPITHELIOSIS” A: Low-power view of this core biopsy shows what appear to be areas of adenosis admixed with apocrine cysts.
