To show the histopathological correlation of non palpable injuries, and being suspicious of malignity and shown through mastography in the Hospital General de México, through percutaneous biopsies with 11G cutting thick needle and vacuum through sterotaxy (BACVE).

Material and methods:

80 BACVE of patients, shown through mastography, age ranging between 32 and 71 years old, from January 1st, 2005, to December 31st, 2007, using a GE analogical mastographer with digital vertical stereotaxy and with a Mammotome Biopsy equipment. Findings were micro-calcifications, nodules, asymmetrical densities and destruction distortion; and being classified in the categories BI-RADS 3, 4 and 5.


80 patients were studied, findings were 38 micro calcifications (47.5%), 37 nodules (46.25%) and an asymmetrical density (1.25%). 66 injuries were benign (82.5%) and 14 malign (17.5%), the age group more affected was younger than 39 years old. The ratio between benignity vs. malignity was of 5.7:1. The more frequent malign subtype was the canalicular carcinoma in situ in seven patients (50%). The most common benign lesion was a fibrocystic condition, found in 39 patients (48.75%).


The BACVE is less expensive and invasive, besides if the diagnosis is a carcinoma, tumor markers may be obtained as well as hormonal receptors that provide a predictive value and a prognosis to plan a specific treatment.
