Ultrasound (US)-guided breast biopsy has become the main method for diagnosing breast pathology, and it has a high diagnostic accuracy, approaching that of open surgical biopsy. However, methods for confirming adequate lesion retrieval after US-guided biopsy are relatively limited and false-negative results are unavoidable. Determining imaging-pathology concordance after US-guided biopsy is essential for validating the biopsy result and providing appropriate management. In this review article, we briefly present the results of US-guided breast biopsy; describe general aspects to consider when establishing imaging-pathology concordance; and review the various categories of imaging-pathology correlations and corresponding management strategies.

Breast ultrasound and mammography are established procedures for the diagnosis of breast masses while new technology is opening the door for early cancer diagnosis. The limitation of ultrasound and mammography is that they are only based on physical properties. Recently, using a color doppler system, detection of color flow signal and a resistance index that depend on the blood flow and the blood velocity was applied for diagnosis of breast malignancy. Sixty-five patients admitted for breast surgery were studied. The final diagnosis was made by pathology for thirty malignancies and thirty-five benign lesions. The color doppler measurements on the breast lesions were made preoperatively. The following parameter were assessed :flow velocity, color signal grade and resistance index. The results are as follows: 1) Color signals were detected in twenty-four of the thirty malignancies and in seven of thirty-five benign lesions. 2) Malignant lesions showed a significantly higher maximum velocity (mean=12.52 cm/sec vs 6.34 cm/sec). 3) The resistance index values in the malignancies was higher compared to that in the benign lesions (P < 0.01), a cutoff point 0.6 was used. 4) The color signal grade was grade 0 and I in thirty-four cases of the benign breast lesions (97%) and grade II and III in fifteen of the malignant breast lesions (50%). 5) In breast cancer, the color signal was detected more often in large masses above 2 cm is size,but the result was not statistically significant (P > 0.05). Color doppler flow examination is a useful method for evaluation of benign and malignant breast lesions.

OBJECTIVETo observe and analyze the pathohistological characteristics of capsules which formed around the mammary prosthesis with different contents. And to provide the selective basis for ideal and safe prosthesis in clinical practice.

METHODS20 specimen of the capsules were taken from 20 cases who receive the operation of prothesis removal for different reasons. HE, Masson and Mallory staining were used to analyse the tissue structure and characteristics under the light microscope.

RESULTSThe common structure including the collagen fibers accumulation, inflammatory cells infiltration and the capillary hyperplasia were found in all specimen. A layer of squamous epithelium-like cell was detected in some specimen. The specific characteristics were also found in different capsules formed around different prosthesis. In the capsules around vegetable oil prosthesis, there was excessive collagen fiber accumulation, and the capsules were much thicker. In the PVP (polyvinylpyrolidone) prosthesis capsules, there was severe inflammatory cell infiltration, and the number of eosinophilic granulocyte increased obviously. In the silicone gel and saline prosthesis capsule, the collagen fibers were well-arranged and the inflammatory cells were much less. Synovial metaplasia was detected in two cases.

CONCLUSION1. The capsules form around the prosthesis in all cases after mammary augmentation. 2. There will be synovial metaplasis in some cases, for vegetable oil prosthesis, the collagen over-accumulated which lead the capsules become thicker and harder. So it is not a kind of ideal mammary prothesis. 4. The severe infiltration of the inflammatory cells especially the large quantity of eosinophilic granulocyte indicate the possibility of the delayed hypersensitive reaction mediated by eosinophilic granulocyte. Cautious attitude should be taken during application.

PURPOSE: The purpose of this study is to evaluate the use of second-look ultrasonography (US) for investigating additional suspicious lesions detected on preoperative staging magnetic resonance imaging (MRI) for breast cancer. METHODS: Between September 2008 and August 2010, 1,970 breast MRIs were performed at our medical institution for the evaluation of breast cancer before surgery. Second-look US was recommended for 135 patients with 149 suspicious lesions, following the MRI interpretation, and 108 patients with 121 lesions were included in this study. The detection rate on second-look US, according to the lesion type, diameter, and histopathological outcome, was analyzed. RESULTS: Of the 121 lesions considered in this study, 97 (80.2%) were diagnosed on MRI as masses and 24 (19.8%) as non-mass-like lesions; 105 lesions (86.8%) were correlated and 16 (13.2%) were not correlated with the findings of second-look US. Of the 105 correlated lesions, 29 (27.6%) were proven to be malignant and 76 (72.4%) were benign. Although a greater number of large malignant lesions were correlated on second-look US than small benign lesions, there was no statistically significant difference according to lesion diameter or type, as seen on MRI or pathology. CONCLUSION: We have concluded that second-look US is a useful diagnostic tool for lesions incidentally detected on breast MRI, as in this study, it could identify 86.8% of the MRI-detected breast lesions.
