DCIS, “healing.”
A:
Prominent periductal fibrosis and chronic inflammation.
B,C:
Severe
periductal fibrosis with lymphocytic reaction. The epithelial element is relatively attenuated
(C)
.
D:
Scar composed of collagen and elastin fibers with calcifications at the site of “healed” DCIS. Images
(A–D)
are from a single specimen.
E:
Marked periductal fibrosis with residual necrotic DCIS.
F:
Concentric fibrosis forms a dense calcified scar with sclerosing entrapment of carcinoma cells.
Note periductal lymphovascular channel involvement by tumor cells. No invasive carcinoma was
identified elsewhere in this case.
