Percutaneous excisional breast biopsy.

Background: The utility of the vacuum-assisted breast biopsy device (VABB) under stereotactic guidance is well established. We hypothesized that the complete removal of small benign lesions under ultrasonography guidance in an outpatient setting could be obtained with minimal morbidity with the multidirectional hand held vacuum-assisted biopsy.

Methods: Patients enrolled in this study underwent an ultrasound-guided minimally invasive excisional breast biopsy through a 3-mm incision.

Intraoperative touch preparation for sentinel lymph node biopsy: a 4-year experience.

Background: The optimal technique for intraoperative pathologic examination of sentinel lymph nodes (SLNs) is still controversial. Recent small series report sensitivity between 60% and 100% for various techniques. The aim of this study was to evaluate our long-term experience with touch preparation cytology (TPC) and frozen section (FS) in the intraoperative examination of SLNs for breast cancer.
