title: Wire-guided biopsies of nonpalpable breast lesions.
abstract: The purpose of this study was to review the results of mammographic wire-guided biopsies of nonpalpable breast lesions and the features of the lesions in the preoperative examinations. Sixty women, mean age 50.2 years (range 31 to 74), underwent a wire-guided biopsy of the lesion. Twenty-nine patients had preoperative fine needle aspiration of the lesion. The radiographic diagnosis was correct in 33 patients (55%); 25 had breast cancer and 8 patients had a benign lesion. In 9 of the 14 patients with clustered microcalcifications in mammography and in 13 of the 15 patients with a mass noted in mammography, the cytological examination was correct. Nonpalpable mammographic masses with regular borders and normal fine needle aspiration examination do not require biopsy. In malignant mammographic appearances associated with a normal fine needle aspiration examination, biopsy of the lesion should always be done.
