Figure 2: Ultrasound images of the right axilla of a 65-year-old woman with infiltrating lobular carcinoma show (a) a round lymph node (arrows) with a 5 mm cortex, (b) a 25 g FNA needle (arrows) traversing the cortex of the node, and (c) the open trough (arrows) of a 12 g core biopsy needle in the node. The FNA was single entry. The core was 1 pass. The FNA cytology was negative but the core biopsy was positive for malignancy; 7 of 18 lymph nodes were positive at axillary dissection performed less than 2 months after the biopsy.
