| | Ductal Carcinoma in situ (Low Power)
|
• This low power view shows several large ducts containing microcalcifications (arrows).
• The blackish discoloration at the edge of the tissue is due to the application of silver nitrate as a method of marking the margin of resection.
• Although not obvious at this power the ducts are lined by abnormal cells of one type, rather than the usual myotepithelial and epithelial cell layers.
• The diagnosis of carcinoma in situ cannot be made at this magnification.
