Ductal Carcinoma in situ (Low Power)

Ductal Carcinoma in situ (Low Power) • This shows a very large duct containing scant eosinophilic debirs. • The lining cells show occasional tiny micropapillations (arrows). • At this power the nuclei can be seen hanging into the lumen, when they should be at the basement membrane side of the epithelium. • The diagnosis of ductal carcinoma in situ cannot be made at this magnification.
