The use of screening mammography for the detection of early carcinoma of the breast the dramatically increased during the past several years. Surgeons are increasing performing biopsy on nonpalpable lesions of the breast. Biopsy directed by
needle
localization has become the procedure of choice for obtaining abnormal mammary tissue for histologic examination.
A retrospective analysis of 24 needle localization biopsies for nonpalpable mammographic microcalcification of the breast June 1992 and May 1993 at the department of general surgery, Korea University Hospital was performed. We have performed the
needle
localization biopsy in more than 3 microcalcifications of the mammography. Because any errors in aligning the specimen to its roentgenogram could result in failure to sample and microscopically examine the area of the microcalcifications, we
compared
the specimen from a needle localized biopsy of the breast with its roentgenogram to locate the area of microcalcification with the specimen.
The prevalent age of mammographic microcalcifications was forth to sixth decades(79%). Mammographic findings were microcalcifications only in 11 cases, mass with microcalcifications in 8 cases, and asymmetric distorsion with microcalcifications
in
4
cases. Cancer was identified in 4 cases(16.7%), TNM stage I. Cancer was identified in 18% of biopsies done for microcalcifications only, only, in 11% of those done for mass with microcalcifications, and in 25% of those done forasymmetric
distorsion
with
microcalcifications. Operations were excision in 20 cases(84%), quadrectomy with axillary dissection in 2 cases(8%), and modified radical mastectomy in 2 cases(8%). Complications accordig to a needle localization were electrocautery burn in 3
cases(12.5%), needle dislogement in 1 case(4%), and hematoma in 1 case(4%). There was no cases of wound infection and the failure to remove the lesion.
As a results, the use of mammographic screening for carcinoma of the breast can result in the discovery of nonpalpable lesions within the breast, we recommend a Hook wire neelde localization biopsy for more than 3 microcalcification with or
without
other lesions in the mammographic screening.
