[Stereotaxic mammary microbiopsy. I. Technical aspects].

The authors present a review of the literature about the procedure of stereotactic core breast biopsy. Developed since the beginning of the 1990s, this histopathological sampling technique presents numerous advantages. Its low cost, its simplicity and its diagnostic efficacy are the main arguments for its development. The diagnostic efficacy confirmed on clinical trials (see 2nd part of article) must be preserved if core biopsy is performed routinely. This means avoiding wrong choices in indications and respecting evaluated procedures.
