Objective: This study was designed to evaluate the effectiveness of complete removal and factors affecting the presence of a residual mass and complications after ultrasound-guided vacuum-assisted percutaneous removal of benign breast lesions.
Methods: We retrospectively evaluated ultrasound images and medical records of 263 breast masses from 199 patients that were removed with an ultrasound-guided vacuum-assisted device. All lesions were assumed as benign on ultrasound imaging or had been confirmed as benign by a previous core needle biopsy. The influence of the size, distance from the nipple, number of lesions removed at a time, and pathologic diagnosis of all of the removed masses on the completeness of the removal and the presence of complications was analyzed. The Mann-Whitney U test was used in the statistical analysis.
Results: The complete removal rate for ultrasound imaging immediately after the procedure was 95.8%, and the rate at more than 6 months for follow-up ultrasound imaging was 92.3%. Larger lesions, lesions closer to the nipple, and cases in which multiple lesions were removed at a time showed the presence of more residual lesions. Lesions closer to the nipple and cases in which multiple lesions were removed simultaneously developed more hematomas (P < .05).
Conclusions: Ultrasound-guided vacuum-assisted percutaneous excision showed high effectiveness for the removal of benign breast masses. However, more attention should be given to certain lesions to increase the efficacy.

: B3 breast lesions, characterized by uncertain malignant potential, pose a significant challenge for clinicians. With the increasing use of preoperative biopsies, there is a need for careful management strategies, including watchful waiting, vacuum-assisted excision (VAE), and surgery. This study aims to assess the concordance between preoperative biopsy findings and postoperative histology, with a focus on evaluating the positive predictive value (PPV) for malignancy in B3 lesions.

Background: Ultrasound‑guided vacuum-assisted excision (UGVAE) and breast biopsy are widely used for the diagnosis and treatment of both benign and suspicious breast lesions. In this retrospective study, we aimed to determine the safety of UGVAE for benign breast lesions and provide guidance for clinical practice.
Methods: We analyzed clinical and pathological data of female patients who had undergone UGVAE between January 2015 and December 2017 at our institution.

Introduction: Breast pseudoaneurysm is a rare complication following breast interventional procedures such as core biopsies and vacuum-assisted biopsies. The occurrence of pseudoaneurysm increases with the conditions of increased breast vascularity like cancer, pregnancy and lactation.
Case Report: We present two cases of pseudoaneurysm formation secondary to core biopsies of the breasts.

Intraductal papillomas (IP) are benign breast tumors that can occur in adolescents and young women, but they are extremely rare in pediatric age group and their occurrence in pediatric patients is not well documented in the medical literature [1,2]. The standard approach for IPs in teenagers involves conservative management with careful monitoring and follow-up imaging. However, in select cases, surgical intervention may be warranted to confirm the diagnosis and prevent complications such as bleeding or infection [3,4].

Purpose: To compare different biopsy systems with different-sized needles by determining the weight of the tissue cores, which is one of the important factors for precise pathological diagnoses, and to provide a rationale for choosing the appropriate breast biopsy system with the appropriate needle for breast cancer biopsy.
Methods: Six different vacuum-assisted biopsy (VAB) systems and one core needle biopsy (CNB) system with different-sized needles in different modes were compared, representing 15 total combinations. Tissue cores were obtained from a chicken breast phantom, which is a common substitute for human breast tissue.
