Abstract

The purpose of this study was to evaluate sonographic features of ductal carcinoma in situ diagnosed percutaneously at ultrasonographically guided large core needle biopsy. Of 619 biopsies, 203 breast carcinomas were diagnosed, of which nine were pure ductal carcinoma in situ. All ductal carcinoma in situ lesions appeared sonographically as hypoechoic masses without a pseudocapsule. Grade 1 lesions (n = 2; mean size, 9.5 mm), grade 2 lesions (n = 4; mean size, 18 mm) and grade 3 lesions (n = 3; mean size, 32 mm) had means of 0, 1, and 5 malignant sonographic features, respectively. Ductal carcinoma in situ appeared mammographically as a mass, with two of four grade 2 lesions and all grade 3 lesions demonstrating suspicious microcalcifications. One grade 3 ductal carcinoma in situ was spiculated. In conclusion, ductal carcinoma in situ lesions tended to show more malignant mammographic and sonographic features as histologic grade and size increased.
