  • Title: Pathologic correlation in mammographically directed breast biopsies.
    Author: Symonds DA, Copeland BE, Drane A, Kaplan GN, Graham RR.
    Journal: Arch Pathol Lab Med; 1992 Jan; 116(1):28-32. PubMed ID: 1734830.
    Abstract:
    In a series of 1137 diagnostic breast biopsy specimens in a 2-year period, nearly half (n = 534) underwent specimen mammography. Calcifications were found in 48% of the specimen mammograms. In a quarter of the cases, calcification was a marker either for carcinoma or a significant precursor lesion. Moreover, in the majority of these malignancies, calcifications were markers of preinvasive carcinoma. In another quarter of cases, some form of proliferative ductal hyperplasia accounted for calcifications, and in the remainder, cysts and miscellaneous other conditions accounted for calcifications. The yield of malignancy was much lower in noncalcified specimens (12%). A nodular or asymmetric density proved to be a fibroadenoma in 30% of cases. However, the majority of cases had less well-defined changes, probably representing some form of lobular fibrosis. We found submission of a duplicate specimen mammogram with the breast biopsy specimen to pathology to be a significant adjunct to correlation. The abnormal area is marked on the mammogram by the radiologist for the pathologist. This is particularly helpful for localizing noncalcified stromal abnormalities. Calcifications are most easily and reliably isolated by serial slicing and performing another radiograph of the slices.
