Atypical Ductal Hyperplasia Diagnosed at Sonographically Guided 14-Gauge Core Needle Biopsy of Breast Mass (original) (raw)

ercutaneous imagingguided core needle biopsy is increasingly being used as a faster, less in vasive, and less expensive alter native to surgical biopsy for the histologic assessment of breast lesions [1]. This technique has been proved reliable and accurate in the diagnosis of both benign and malignant diseases of the breast [2-4]. However, the core needle biopsy finding of atypical ductal hyperplasia (ADH) is less reliable owing to histologic underestimation of malignancy, that is, upgrade of the result to ductal carci noma in situ (DCIS) or invasive cancer at surgical excision. The rate of underestimation of ADH has been reported to be 11-75% for 14gauge core needle biopsy [5, 6]. Therefore, there seems to be a consensus on the need for surgical excision when ADH is diagnosed at core needle biopsy [7]. The widespread practice of mammog raphic screening for breast cancer has led to
