Clusters of indistinguishable, powdery, dust-like microcalcifications on the mammograms.
The clusters of powdery, ducts-like microcalcifications are formed within the fluid accumulated in the distended TDLUs when the fluid has been produced by the Grade 1 cancer in situ cells (50% of all powdery calcification cases) or in benign sclerosing adenosis (50%).
This lecture describes the pathophysiologic processes leading to the formation of the microcalcifications, it details the differential diagnostic problems and the solution to the problem. Numerous practice cases and teaching points are provided throughout the lecture.
