[Application of guide wire location under mammography for a resection of subclinical breast lesions].

Objective: To investigate the value of guide wire location under mammography for a resection of subclinical breast lesions.

Methods: A total of 79 patients presenting with abnormal mammography but unpalpable lesions received a guide wire pre-operative location under mammography. And 82 lesions were successfully located and resected for pathological examination.

Results: All 82 lesions were located with a high accuracy. The pathological examination revealed breast fibroma (n = 4), mammary gland hyperplasia with calcification (n = 58), intraductal papilloma (n = 2), fat necrosis with calcification (n = 3), mammary atypical hyperplasia (n = 5), breast inflammation (n = 1) and breast cancer (n = 9).

Conclusion: The technique of guide wire location under mammography is highly accurate for pre-operative location of subclinical breast lesions. It is valuable for an early diagnosis of unpalpable breast lesions.
