Abstract

PURPOSE
As film-screen mammography became to.be used widely, more mammographic abnormalities without palpable masses were detected and the need for surgical biopsies increases. We intended to study the mammographic findings and pathologic diagnosis together with the preoperative localization procedures used in these cases.
MATERIALS AND METHODS
From Feb. 1987 to Mar. 1993 localization of breast lesion using Breast Needle/Wire Localizer as done in 179 cases. All cases were proven pathologically through surgical biopsy.
RESULTS
In these cases, microcalcification(52.0%), mass(29.6%), architectural distortion(2.2%), or combination of the above(16.2%) was observed on film mammogram. Most frequent lesion site was upper outer quadrant(53.1%), followed by upper inner quadrant(25.7%), subareolar area(7.8%), lower outer quadrant(6.7%) and lower inner quandrant(6.7%) in decreasing order of frequency. Cranial(85.5%) approach for needle localization was mostly used but other approaches such as caudal(5.6%), lateral(5.0%) and medial(3.9%) were also used. A total of 24 cases was malignant(13.4%), and among them there were 14 cases of intraductal carcinoma, 1 intralobular carcinoma, 8 invasive ductal carcinoma and 1 invasive Iobular carcinoma.
CONCLUSION
With the use of Breast Needle/Wire Localizer , safe, simple and precise localization of nonpalpable breast lesion can be achieved. It makes breast biopsy possible with minimal resection of breast tissue therefore minimizing disfigurement of the breast resulting from operation.
