Back ground: Breast microcalcifications are considered an early mammographic sign of breast cancer which are present with tiny bright spots of different morphology. In an ultrasound (US) image, the presence of microcalcifications within breast is an important indicator of malignancy.With an improved sonographic detection of microcalcification, ultrasound could be used for biopsy guidance for target sampling of tissue containing suspicious microcalcifications. If the biopsied lesions had a suspicious microcalcifications, specimen radiograph is mandatory to confirm the presence of microcalcifications in which a core containing any calcification on specimen radiography was defined as asuccessfully retrieved core. 14-G(Gauge) semi-automated core needle biopsy(CNB) device is less costly than other biopsy device. Methods:A prospective study was conducted on thirty female patients with thirty- two lesions their mean age was 48.53 years (age range, 21-75 years) radiologically classified as BIRADS (Breast Imaging Reporting and Data system) 4 (b, c) and5 from those referred to women imaging health unit in Radiology department for Sono- Mammography and those patients were referred from the inpatient wards and outpatient clinics of the surgery departments during the period from September 2018 till May 2019.All patients underwent conventional digital mammography and B-mode ultrasound examination and Ultrasound guided biopsy, specimen radiography then tissue samples were sent to histopathology department in which slide picture was done.Then (28) females done surgery and (2) patient still for follow up. Results: Radiological diagnosis of our lesions using BIRADS(Breast Imaging Reporting and Data system) categorical method were identified as two intermediate suspicious lesions (BIRADS 4B 6.3 %), twelve moderate suspicious lesions (BIRADS 4C 34.4 %), and 19 highly suggestive of malignancy lesions (BIRADS 5 59.4 %). Retrieval rate of calcifications according to specimen radiography were successfully retrieved in 30/32 lesions (93.8 %) and confirmed on specimen radiography .CNB( core needle biopsy) identified 28 lesions (87.5 %) malignant and four (12.5 %) benign lesions. Distribution of lesions according to pathological diagnosis in successful and fail retrieval group, the successful retrieval group comprised 26 malignant (22 IDC(Invasive ductal carcinoma), 2 DCIS(Ductal carcinoma Insitu), 2 ILC(Invasive Lobuler carcinoma) ) and four benign lesions.After CNB( core needle biopsy), 30 lesions underwent surgical excision and final pathology results were provided. All 24 IDC on 14-G semi-automated CNB (core needle biopsy) were confirmed to be IDC(Invasive ductal carcinoma) on final pathology. Of the two DCIS(Ductal carcinoma Insitu) on US(Ultrasound) guided CNB( core needle biopsy), one DCIS, were upgraded to IDC, the other one confirmed to be DCIS on final pathology,the two ILC were confirmed to be ILC on final pathology.Of the four benign lesions, the two ADH(Atypical Ductal hyperplasia) underwent surgical excision, finally diagnosed as DCIS,the other two benign lesions (fibroadenoma and fibroadenosis) their BIRADS assessments were category 4C and were recommended for follow-up.The overall accuracy of US-guided 14-G(Gauge) semi-automated CNB( core needle biopsy) was 90.0 % (27/32). Conclusion: The present study confirms the good retrieval rate (93.8%) of US-guided 14-G semi-automated CNB and diagnostic accuracy of (90.0%). Thus, this could be useful procedure for suspicious microcalcifications apparent on sonography.Specimen radiography proved to be a great help in deciding the accurate retrieval of microclcifications by core biopsy. It should be done in all cases of core biopsy for calcifications with marking of the core containing calcifications to be specially assessed by histopathology. We should try to do core biopsy before using VAB (Vaccum-Assisted Biobsy)for calcifications if well seen by ultrasound.

Abstract Encapsulated papillary carcinoma (EPC) is a rare, clinically indolent breast malignancy most common in postmenopausal women. Absence of myoepithelial cells at the periphery is a characteristic feature. Mammographically, EPC typically presents as a mostly circumscribed, noncalcified, dense mass that can have focally indistinct margins when there is associated frank invasive carcinoma. Ultrasound shows a circumscribed solid or complex cystic and solid mass, and occasional hemorrhage in the cystic component may produce a fluid-debris level; the solid components typically show intense washout enhancement on MRI. Color Doppler may demonstrate a prominent vascular pedicle and blood flow within solid papillary fronds. Encapsulated papillary carcinoma can exist in pure form; however, EPC is often associated with conventional ductal carcinoma in-situ and/or invasive ductal carcinoma, no special type. Adjacent in-situ and invasive disease may be only focally present at the periphery of EPC and potentially unsampled at core-needle biopsy. In order to facilitate diagnosis, the mass wall should be included on core-needle biopsy, which will show absence of myoepithelial markers. Staging and prognosis are determined by any associated frankly invasive component, with usually excellent long-term survival and rare distant metastases.

AbstractBackground: Breast cancer is the female cancer with the highest mortality. While early detection is a public health priority in Western European countries, a screening program in our country has yet to be implemented. The best diagnostic accuracy is achieved through the use of triple assessment: clinical examination, imaging, and core-needle biopsy where indicated. Prognosis is influenced by clinical, histological, and biological factors, and therapy is most effective when individually tailored.Aim of the study: To analyze the clinical, histological, and immunohistochemical characteristics of the biopsied nodules and summarize our experience from the last three years.Material and Methods: We retrospectively analyzed data from 137 patients who underwent core-needle biopsy between 2017 and 2019. Imaging score was assigned based on ultrasound examination or mammography. Clinical and pathological parameters were recorded, followed by statistical processing of the data.Results: The mean age of the patients was 58 ± 14 years, lesions had a mean size of 22.83 ± 14.10 mm. Most nodules (n = 63, 47.01%) were located in the upper-outer quadrant, and bilateral presence was found in 4 (3.08%) cases. We found a significant positive correlation between lesion size and the patients’ age (Spearman r = 0.356; 95% CI 0.186, 0.506; p = 0.000). The malignancy rates within the Breast Imaging Reporting and Data System (BI-RADS) categories were as follows: 0% for „4a”, 31.58% for „4b”, 71.42% for „4c”, and 97.72% for „5”. Most malignancies (n = 73, 78.35%) were represented by invasive ductal carcinoma of no special type, 58.43% (n = 52) were grade 2, 89.13% (n = 82) were estrogen receptor positive, and Luminal B-like type was the most common (n = 63, 78.75%).Conclusions: The mean size of tumors was larger than the average size at discovery described in the literature. In our region, age and tumor size are positively correlated. Preoperative histological results may indicate the reliability of the imaging risk stratification system. Most cases can benefit from adjuvant endocrine therapy.
