PURPOSE: Increased technologic capabilities have allowed for the expanded use of ultrasound beyond simple differentiation of a lesion as solid versus cystic nature, allowing us to classify lesions into various categories based on a number of descriptive features. The purpose of this study was to investigate whether to predict the preoperative prognosis of breast cancer through the correlation between ultrasonographic images and the grade of malignancy. MATERIALS AND METHODS: The patient population for this study consisted of 107 patients with infiltrative ductal carcinoma who were evaluated using ultrasound technology. Ultrasonographic findings were divided as follows: Type I, round or oval shape and regular border; Type II, partially round or oval shape and partially irregular border; and Type III, irregular shape and irregular border. RESULTS: 1. The frequency of grade 1 (G1) was significantly higher in the Type I group than the othergroups. 2. In the 2.0 cm sized mass, the lymph node metastasis rate was significantly lower in the Type I group than the other groups. 3. In all the groups, Estrogen receptor (ER) positivity was insignificant regardless of tumor size and type. 4. In the 2.0 cm sized mass, c-erbB-2 positivity was significantly lower in the Type I than the other groups. There was no clear difference among the three groups in tumors greater than 2.0 cm in size. CONCLUSION: These results show that our classification of ultrasonographic images reflect the grade of malignancy in terms of clinicopathological features in breast cancers less than 2.0 cm in size. Therefore, ultrasonographic findings may help predict the preoperative prognosis in T1 size breast cancer, although further study is required.

PURPOSE: Absorbable retaining thread (ART) needle localization utilizes a guiding needle with a thread; this technique was invented to reduce patient discomfort and wire migration. We investigated the feasibility of ultrasound (US)-guided ART needle localization for nonpalpable breast lesions. METHODS: ART needle localization was performed for 26 nonpalpable breast lesions in 26 patients who were scheduled to undergo surgical excision the day after localization. Seventeen breast lesions were initially diagnosed as invasive ductal carcinoma, six as ductal carcinomas in situ, and one as fibrocystic change. The other two cases without an initial pathologic diagnosis had suspicious US features, and excision was planned concomitantly with contralateral breast cancer surgery. The primary outcome was the technical success rate of ART needle localization confirmed by US immediately after the procedure, and the secondary outcomes were the percentage of clear margins on pathology and the complication rate of ART needle localization. RESULTS: The technical success rate of ART needle localization was 96.2% (25 of 26 patients), and the ART was located 1 cm away from the mass in one patient (3.8%). The lesions were successfully removed with clear margins in all 26 patients. No significant complications related to ART needle localization were observed. CONCLUSION: ART needle localization can be an alternative to wire needle localization for nonpalpable breast lesions.

OBJECTIVE:
To investigate the early diagnosis of breast cancer with nonpalpable tumor.
METHODS:
Forty-six cases of clinical nonpalpable tumor were examined by mammography and sonography.The cases of nipple discharge were also examined by fiberoptic ductoscopy.
RESULTS:
Breast cancer in 46 cases was diagnosed by pathological examination. Of them, 34 diagnosed with breast cancer were found with nodus, calcification or confused structure, and so on, 5 were considered benign tumor, and 7 were not found lesion by mammography. Thirty-one cases were diagnosed with breast cancer, 6 with benign tumor, and 9 were not found occupying lesion by sonography. Occupying lesions were found in 6 cases of nipple discharge by fiberoptic ductoscopy and were finally diagnosed by biopsy.
CONCLUSION
Mammography and sonography are important methods in early discovering breast cancer. Early diagnosis rate of breast cancer can be elevated by signs of early breast cancer and combined examination of mammograply and sonography.

PURPOSE: This study was designed to determine the rate of ductal carcinoma in situ (DCIS) underestimation diagnosed after an ultrasound-guided 14-gauge core needle biopsy (US-14G-CNB) of breast masses and to compare the clinical and imaging characteristics between true DCIS and underestimated DCIS identified following surgical excision. METHODS: Among 3,124 US-14G-CNBs performed for breast masses, 69 lesions in 60 patients were pathologically-determined to be pure DCIS. We classified these patients according to the final pathology after surgical excision as those with invasive ductal carcinoma (underestimated group) and those with DCIS (non-underestimated group). We retrospectively reviewed and compared the clinical and imaging characteristics between the two groups. RESULTS: Of the 69 lesions, 21 were shown after surgery to be invasive carcinomas; the rate of DCIS underestimation was 30.4%. There were no statistically significant differences with respect to the clinical symptoms, age, lesion size, mammographic findings, and ultrasonographic findings except for the presence of abnormal axillary lymph nodes as detected on ultrasound. The lesions in 2 patients in the non-underestimated group (2/41, 4.9%) and 5 patients in the underestimated group (5/19, 26.3%) were associated with abnormal lymph nodes on axillary ultrasound, and the presence of abnormal axillary lymph nodes on ultrasound was statistically significant (P=0.016). CONCLUSION: We found a 30.4% rate of DCIS underestimation in breast masses based on a US-14G-CNB. The presence of abnormal lymph nodes as detected on axillary ultrasound may be useful to preoperatively predict underestimation.

Primary neuroendocrine carcinoma of the breast (NECB) is a very rare type of invasive breast carcinoma. Most NECBs appear on breast imaging as solid masses of varied shapes and margins, and have worse clinical outcomes than does invasive ductal carcinoma, not otherwise specified. However, there have been no reports to date regarding NECB with features of inflammatory breast carcinoma. Here, we describe the clinical, radiol-ogic, and pathologic findings of the first reported case of primary NECB presenting as inflammatory breast carcinoma. The patient complained of diffuse right breast enlargement and erythema. Mammography identified severe breast edema and axillary lymphadenopathy. Ultrasound detected an irregular, angular, hypoechoic mass with dermal lymphatic dilatation. On magnetic resonance imaging, the mass had rim enhancement and the entire right breast showed heterogeneous enhancement with malignant kinetic features. Pathology identified the mass as a primary NECB with positive for synaptophysin, CD56, estrogen and progesterone receptors.

PURPOSE: To evaluate the contrast-enhanced MR findings of lesions associated with a radial scar and to compare the MR findings with the histopathology results. MATERIALS AND METHODS: From Mar. 2001 to Sep. 2005, 8 patients with a surgically proven radial scar who had undergone MRI, mammography, and ultrasonography were enrolled in this study. The morphological findings and dynamic enhancement pattern of the time-intensity curve were retrospectively reviewed using non-contrast and contrast-enhanced MRI. Mammography and ultrasonography were also analyzed according to the BI-RADS category and correlated with the histopathological diagnosis. RESULTS: The age of the patients ranged from 42 to 53 years (mean, 47 years). Five patients presented with a left breast lesion and the others presented with a right breast lesion. The histopathological diagnosis associated with the radial scar were fibrocystic changes (n=1), adenosis (n=2), atypical ductal hyperplasia (n=2), lobular carcinoma in situ (n=1), ductal carcinoma in situ (n=1), and invasive ductal carcinoma (n=1). In all patients, architectural distortion without microcalcification was observed with mammography. Irregular shaped hypoechoic lesions with an indistinct, spiculated, or angular margin was observed in all patients with ultrasonography. Posterior shadowing was observed in 4cases. MR enhancement revealed two cases with foci enhancement (adenosis and fibrocystic change), five cases with non-mass-like focal enhancement (fibrocystic change, atypical ductal hyperplasia, lobular carcinoma in situ, ductal carcinoma in situ, invasive ductal carcinoma), and one irregular homogeneous mass enhancement (atypical ducal hyperplasia). The time-signal intensity curves are as follows: persistent type (n=2), adenosis, and fibrocystic changes, respectively; plateu type (n=4), one adenosis, two atypical ductal hyperplasia, and one ductal carcinoma in situ; and washout type (n=2), lobular carcinoma in situ, and invasive ductal carcinoma, respectively. CONCLUSION: Although a combined benign or malignant pathology with a radial scar was not predicted on the preexisting image modality, contrast-enhanced MRI can help to predict a combined benign or malignant pathology with a radial scar using the morphological findings and the dynamic enhancement type of the time-intensity curve.

PURPOSE: To identify predictive factors of upstaging from diagnosed ductal carcinoma in situ (DCIS) to invasive cancer after surgical excision. METHODS: One hundred seventy-four patients diagnosed with DCIS based on biopsies between January 2009 and December 2014 were evaluated. Patients' clinicopathological variables were assessed to identify predictive factors of invasive carcinoma from final pathology. RESULTS: One hundred seventy-four cases of DCIS were included. Of these, 42 were upstaged to invasive carcinoma on the final excision. Preoperative features such as age 40 years or younger at diagnosis, presence of a palpable mass, ultrasonography (USG)-guided core needle biopsy, tumor size ≥20 mm on USG, high grade DCIS, cribriform DCIS, comedo necrosis, presence of intraluminal calcification, estrogen receptor negativity, progesterone receptor negativity and triple-negative subtype were significantly associated with the risk of invasive carcinoma. Multivariate analysis showed that a tumor size ≥20 mm on USG and triple negative subtype were independently associated with upstaging. CONCLUSION: Tumor size ≥20 mm on USG and triple-negative subtype were independently associated with the upstaging of DCIS to invasive cancer.

PURPOSE: The purpose of this study was to evaluate the ultrasonographic features of pure ductal carcinoma in situ (DCIS) of the breast and to evaluate the correlations of ultrasonographic features with pathologic and biological features. METHODS: A total of 141 lesions in 138 women with pure DCIS who underwent preoperative breast ultrasonography were retrospectively reviewed. Ultrasonographic features were analyzed using the American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) ultrasonography lexicon and the diagnostic criteria of the Japan Society of Ultrasonics in Medicine. Pathologic features including the nuclear grade and presence of comedonecrosis were evaluated. Biological markers including estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) status, as well as the Ki-67 index, were recorded. Ultrasonographic features were compared with pathologic findings and biological markers using the chi-square test. P-values of < 0.05 were considered to indicate statistical significance. RESULTS: Of the 141 lesions, 75 (53.2%) were mass lesions, 56 (39.7%) were non-mass lesions, and 10 (7.1%) were not visible. The most common feature of the mass pattern was a mass with irregular shape (32.6%), an indistinct margin (27.7%), and hypoechogenicity (37.6%). Microcalcifications were observed in 48 cases (36.6%) as an associated feature. Calcifications outside of a mass were more common than calcifications within a mass. Ultrasonographic microcalcifications and ductal changes were frequently observed in non-mass lesions. Ultrasonographic non-mass lesions were associated with high-grade DCIS (P=0.004) and the presence of comedonecrosis (P=0.006). Microcalcifications were significantly associated with high-grade DCIS (P < 0.001), the presence of comedonecrosis (P < 0.001), an elevated Ki-67 (P < 0.001), and HER2 positivity (P=0.003). CONCLUSION: The most common ultrasonographic feature of pure DCIS was an irregular, hypoechoic mass with an indistinct margin. Ultrasonographic microcalcifications and ductal changes were more frequent in non-mass lesions, which were correlated with poor prognostic factors, such as a high nuclear grade, comedonecrosis, HER2 positivity, and an elevated Ki-67 index.

A paraffin injection is regarded as to be a simple and effective method of breast augmentation. However, there are few reports on the long-term complication of a paraffin injected breast. The generation of breast cancer from a paraffinoma of the breast is rare, even though there is no clear evidence to suggest any relationship between a paraffin injection and breast cancer. We encountered a case of infiltrative ductal carcinoma arising from paraffinoma tissues. A 49-year-old woman had undergone bilateral breast augmentation by paraffin injection 20 years earlier. She presented with bilateral diffuse painless palpable masses with reddish discoloration and painful swelling in her left breast. She had been managed with a bilateral simple mastectomy including the mass. After discharge, the pathology report showed infiltrative ductal carcinoma of the left breast mass. The patient was readmitted for additional surgery, and she underwent a modified radical mastectomy. Ultrasonography is a useful diagnostic tool for detecting a breast mass, particularly in a dense breast. However, ultrasonography has a limitation in the case of a paraffinoma. Through this case, it is necessary to review the radiological (mammography, ultrasonography, magnetic resonance imaging, plain film) appearances and the histopathological feature to help make an accurate diagnosis and to differentiate between a carcinoma and a paraffinoma. In rare cases, a breast ductal carcinoma can be combined with a paraffinoma. Therefore, a paraffinoma must be carefully managed due to the potential risk of a carcinoma.
