Significant sampling error occurs regardless of the type of core biopsy device, number of specimens obtained, histologic–radiographic concordance, mammographic appearance, and complete excision of the lesion as determined by imaging. For this reason, all patients with lobular neoplasia at core or vacuum-assisted biopsy should undergo surgical excision until further differentiating criteria can be determined.

Vacuum-assisted biopsy was more accurate than core needle biopsy in diagnosing papillary lesions, and both sonographic features and core needle biopsy were not sufficiently accurate. Therefore, surgical excision should be performed for the accurate diagnosis of papillary lesions.

Intraoperative Loss of Core Biopsy Clips: Clinical Implications

Intraoperative loss of metallic clips placed at the conclusion of image-guided breast biopsy is unusual but can occur during subsequent surgical excision.

Repeated inability to locate the clip on specimen radiographs after accurate preoperative localization should raise the suspicion that the target clip has been lost, not missed, during surgery, likely because of inadvertent removal of the clip with the suction device
