title: Ultrasound-guided large needle core biopsy of the axilla.
abstract: OBJECTIVE
  To study the diagnostic yield and safety aspects of large needle core biopsy of pathologic lesions in the axillary region using a semi-automatic biopsy gun.
  
  
  METHODS
  A series of 21 consecutive large needle core (14G, 2.1 mm) biopsies of the axilla was evaluated. The biopsies were performed under ultrasound guidance with one (n = 13) or two (n = 8) needle passes. The results were correlated to the clinical, mammographic, ultrasound and surgical histopathologic findings.
  
  
  RESULTS
  In 18 patients, specimens large enough for diagnosis were retrieved. In two patients the specimens were insufficient and non-diagnostic. In one patient with a non-malignant yield the result was false-negative. No neural or vascular injury occurred.
  
  
  CONCLUSIONS
  The procedure might be safely employed in the diagnosis of ultrasonographically demonstrable lesions of the axilla, whenever specimens larger than those obtainable with a fine needle are desired.
