Ductal carcinoma in situ of the breast: correlation between mammographic calcification and tumor subtype.

Abstract

We conclude that the comedo subtype of ductal carcinoma in situ is more likely to be accompanied by linear calcifications than are the noncomedo subtypes, and noncomedo ductal carcinoma in situ is more likely to be associated with granular calcifications than is the comedo subtype when microcalcifications are seen on mammograms. However, there is considerable overlap, and the predominant histologic subtype cannot be predicted on the basis of the microcalcification type with a high degree of accuracy.
