LOBULAR CARCINOMA IN SITU INVOLVING TUBULAR ADENOSIS Figure 6-24 LOBULAR CARCINOMA IN SITU INVOLVING TUBULAR ADENOSIS A: All the tubules in this case were involved by LCIS. Note the elongated, occasionally branching, tubules, which have a somewhat disorganized arrangement at low power. B: Higher...

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 are not...

ADENOMYOEPITHELIOMA, TUBULAR TYPE Figure 7-42 ADENOMYOEPITHELIOMA, TUBULAR TYPE A: This more unusual pattern of adenomyoepithelioma is characterized by numerous tubules clustered together, and percolating through the breast parenchyma. B,C: At intermediate (B) and high (C) power, the tubules are... More about this image found in ADENOMYOEPITHELIOMA, TUBULAR TYPE A: This more unusual pattern of adenomyo...

ADENOID CYSTIC CARCINOMA Figure 8-67 ADENOID CYSTIC CARCINOMA The tubular pattern of adenoid cystic carcinoma is seen at high power. Basement membrane material is present in the pseudolumens of the tubules. More about this image found in ADENOID CYSTIC CARCINOMA The tubular pattern of adenoid cystic carcinoma i...

INVASIVE BREAST CARCINOMA, NST, GRADE 2 Figure 8-2 INVASIVE BREAST CARCINOMA, NST, GRADE 2 This tumor is composed of a mix of tubules and solid nests. The tumor cell nuclei display greater variability than the prior case. More about this image found in INVASIVE BREAST CARCINOMA, NST, GRADE 2 This tumor is composed of a mix of...

INVASIVE BREAST CARCINOMA, NO SPECIAL TYPE (NST), GRADE 1 Figure 8-1 INVASIVE BREAST CARCINOMA, NO SPECIAL TYPE (NST), GRADE 1 This low-power image shows a tumor composed of well-formed tubules with cells that have round, regular nuclei; no mitoses are present. More about this image found in INVASIVE BREAST CARCINOMA, NO SPECIAL TYPE (NST), GRADE 1 This low-power i...

INVASIVE BREAST CARCINOMA, NST, GRADE 1 Figure 8-10 INVASIVE BREAST CARCINOMA, NST, GRADE 1 A: Over 75 percent of this tumor is composed of tubules. B: The tumor cell nuclei are of low nuclear grade; no mitotic figures are seen. C: As would be anticipated, the tumor is strongly and diffusely es...
