[Marking techniques and ultrasound guided mastografía prior to obtaining biopsy breast excisional].
BACKGROUND
Breast cancer is the most common gynecologic malignancy worldwide. Localization under ultrasound guidance or mammography prior to biopsy is one of the procedures used for diagnosis of subclinical malignant or premalignant lesions.


OBJECTIVE
To describe techniques for localization by mammography or ultrasound at our institution, prior to excisional breast biopsy.


METHODS
Localization under ultrasound guidance or mammography from July 1 to December 31, 2008 at the HospitalAngeles del Pedregal. An analysis of the category BIRADS, histopathologic results, the imaging procedure and the surgical approach.


RESULTS
We made 78 procedures. 56% under mammography guidance and 44% by ultrasound. 23% of biopsies with histopathological result of malignancy and 77% were benign, the outcome depended on the category of BIRADS granted. Success depends on the technique of covering the lesion in its entirety and was 100% in our study.


CONCLUSIONS
Localization of nonpalpable lesions of the breast remains a useful procedure for diagnosis of suspicious lesions. The choice of the imaging technique depends on the characteristics of the lesion under study.
