We report the surgical pathology experience with large caliber stereotactic
biopsies for non-palpable breast lesions in 217 patients. The aim is to co
mpare the demographics to another somewhat similar center (#2), and to publ
ished results with the much smaller stereotactic needle biopsies, including
our own historical controls. The large caliber tissue specimens yielded pr
oportionally fewer nonspecific diagnoses, with remaining areas of difficult
y. An evolving diagnostic strategy is outlined. Copyright (C) 1999 by W.B.
