[Comedocarcinoma: a tumor histotype to be reevaluated].

The authors report their experience with clinical mammography in the study of breast cancers, stressing the importance of comedocarcinoma, to date considered an histotype with low incidence (5%). Of late, however, a major increase has been observed in the incidence of this tumoral histotype (14%) which is now ranking second in the overall breast-cancer incidence rate. The diagnostic accuracy of mammography in our series of cases was approximately 85%. A special emphasis is put on structurally dense breast as an intrinsic factor limiting mammographic accuracy. The influence of the histotype on these results is reported. The differential diagnosis with ductal carcinoma is discussed after an anatomo-pathologic review.
