ABSTRACT
PURPOSE:
To evaluate the mammographic and clinical findings of nonpalpable breast cancer. MATERIALS ANDMETHODS:
In 28 of 607 breast cancer patients examined between January 1994 and April 1997, lesions werenonpalpable. We retrospectively analyzed the mammographic, clinical and pathologic features of 25 patients (28lesions) whose mammograms we obtained.RESULTS:
Among these 25 patients (28 lesions) screening was abnormal in22; other symptoms were bloody nipple discharge(n=4), and nipple eczema(n=2). The patients were 34-62 (mean 52)years old. Invasive ductal carcinoma(n=13), DCIS(ductal carcinoma in situ, n-12), Paget's disease (n=2), andLCIS(lobular carcinoma in situ, n=1) were found during surgery. Six of 28 lesions(21%) showed evidence of axillarynodal metastasis;the majority arose from the upper outer quadrant of the breast (n=21). The mammographic findingswere mass (50%), (and mass with microcalcification, 11%); microcalcification(29%); asymmetrical density(14%); andnormal (7%). According to the mammographic density of breast parenchyma, the major finding in the low densitygroup(N1+P1) was mas (9/9), and in the high density group(P2+DY) was microcalcification (12/19).CONCLUSION:
Themost common mammographic findings of nonpable breast cancer were mass (50%) and microcalcification(29%). Itsfeatures varied according to the mammographic density of breast parenchyma;mass was the main finding in the lowdensity group and microcalcification in the high density group.
