2108: Papillary lesions diagnosed at sonography-guided biopsy

Abstract

Objectives: To demonstrate the sonographic features of papillary lesions diagnosed at sonography-guided biopsy (SGB) and to determine the outcome of these lesions and management plan.Methods: The results of 5460 SGB were reviewed to identify cases of papillary lesions. Surgical finding (excisional biopsy, breast-conserving surgery and mastectomy) and follow-up sonographic data were categorized as benign, borderline and malignancy.Results: One hundred ninety-seven (3.6%) of 5460 biopsies exhibited papillary lesions SGB. Among these 197 cases, 100 patients performed surgery (n = 89) or mammotome excision (n = 11), 57 patients had taken the follow-up sonography and remaining 40 patients had no surgery and follow-up study. Malignant lesions were detected in 24%, borderline lesions in 13% and benign lesions in 63% of patients performed surgery. All 57 patients with follow-up sonography had benign papillary lesion. Imaging-histologic discordance was found in nine (14%) of the patients with benign lesion, in one (8%) of the patients with borderline lesion and in four (17%) of patients with malignant lesion.Conclusions: Sonographic findings of papillary lesions diagnosed at SGB are variable from probably benign lesion to suspicious findings. However, SGB results with imaging-histologic concordance may be sufficient to determine the diagnosis and management of papillary lesions with rare exception.
