RESUMO
INTRODUCTION: Benign breast disease (BBD) and high mammographic breast density (MBD) are prevalent and independent risk factors for invasive breast cancer. It has been suggested that temporal changes in MBD may impact future invasive breast cancer risk, but this has not been studied among women with BBD. METHODS: We undertook a nested case-control study within a cohort of 15,395 women with BBD in Kaiser Permanente Northwest (KPNW; 1970-2012, followed through mid-2015). Cases (n = 261) developed invasive breast cancer > 1 year after BBD diagnosis, whereas controls (n = 249) did not have breast cancer by the case diagnosis date. Cases and controls were individually matched on BBD diagnosis age and plan membership duration. Standardized %MBD change (per 2 years), categorized as stable/any increase (≥ 0%), minimal decrease of less than 5% or a decrease greater than or equal to 5%, was determined from baseline and follow-up mammograms. Associations between MBD change and breast cancer risk were examined using adjusted unconditional logistic regression. RESULTS: Overall, 64.5% (n = 329) of BBD patients had non-proliferative and 35.5% (n = 181) had proliferative disease with/without atypia. Women with an MBD decrease (≤ - 5%) were less likely to develop breast cancer (Odds Ratio (OR) 0.64; 95% Confidence Interval (CI) 0.38, 1.07) compared with women with minimal decreases. Associations were stronger among women ≥ 50 years at BBD diagnosis (OR 0.48; 95% CI 0.25, 0.92) and with proliferative BBD (OR 0.32; 95% CI 0.11, 0.99). DISCUSSION: Assessment of temporal MBD changes may inform risk monitoring among women with BBD, and strategies to actively reduce MBD may help decrease future breast cancer risk.

BACKGROUND: Breast cancer-related leptomeningeal disease (BC-LMD) is a dire diagnosis for 5-8% of patients with breast cancer (BC). We conducted a retrospective review of BC-LMD patients diagnosed at Moffitt Cancer Center from 2011 to 2020, to determine the changing incidence of BC-LMD, factors which are associated with the progression of BC CNS metastasis to BC-LMD, and factors which are associated with OS for patients with BC-LMD. METHODS: Patients with BC and brain/spinal metastatic disease were identified. For those who eventually developed BC-LMD, we used Kaplan-Meier survival curve, log-rank test, univariable, and multivariate Cox proportional hazards regression model to identify factors affecting time from CNS metastasis to BC-LMD and OS. RESULTS: 128 cases of BC-LMD were identified. The proportion of BC-LMD to total BC patients was higher between 2016 and 2020 when compared to 2011-2015. Patients with HR+ or HER2 + BC experienced longer times between CNS metastasis and LMD than patients with triple-negative breast cancer (TNBC). Systemic therapy and whole-brain radiation therapy (WBRT) was associated with prolonged progression to LMD in all patients. Hormone therapy in patients with HR + BC were associated with a delayed BC-CNS metastasis to LMD progression. Lapatinib treatment was associated with a delayed progression to LMD in patients with HER2 + BC. Patients with TNBC-LMD had shorter OS compared to those with HR + and HER2 + BC-LMD. Systemic therapy, intrathecal (IT) therapy, and WBRT was associated with prolonged survival for all patients. Lapatinib and trastuzumab therapy was associated with improved OS in patients with HER2 + BC-LMD. CONCLUSIONS: Increasing rates of BC-LMD provide treatment challenges and opportunities for clinical trials. Prospective trials testing lapatinib and/or similar tyrosine kinase inhibitors, IT therapies, and combination treatments are urgently needed.

Importance: Benign breast disease (BBD) comprises approximately 75% of breast biopsy diagnoses. Surgical biopsy specimens diagnosed as nonproliferative (NP), proliferative disease without atypia (PDWA), or atypical hyperplasia (AH) are associated with increasing breast cancer (BC) risk; however, knowledge is limited on risk associated with percutaneously diagnosed BBD. Objectives: To estimate BC risk associated with BBD in the percutaneous biopsy era irrespective of surgical biopsy. Design, Setting, and Participants: In this retrospective cohort study, BBD biopsy specimens collected from January 1, 2002, to December 31, 2013, from patients with BBD at Mayo Clinic in Rochester, Minnesota, were reviewed by 2 pathologists masked to outcomes. Women were followed up from 6 months after biopsy until censoring, BC diagnosis, or December 31, 2021. Exposure: Benign breast disease classification and multiplicity by pathology panel review. Main Outcomes: The main outcome was diagnosis of BC overall and stratified as ductal carcinoma in situ (DCIS) or invasive BC. Risk for presence vs absence of BBD lesions was assessed by Cox proportional hazards regression. Risk in patients with BBD compared with female breast cancer incidence rates from the Iowa Surveillance, Epidemiology, and End Results (SEER) program were estimated. Results: Among 4819 female participants, median age was 51 years (IQR, 43-62 years). Median follow-up was 10.9 years (IQR, 7.7-14.2 years) for control individuals without BC vs 6.6 years (IQR, 3.7-10.1 years) for patients with BC. Risk was higher in the cohort with BBD than in SEER data: BC overall (standard incidence ratio [SIR], 1.95; 95% CI, 1.76-2.17), invasive BC (SIR, 1.56; 95% CI, 1.37-1.78), and DCIS (SIR, 3.10; 95% CI, 2.54-3.77). The SIRs increased with increasing BBD severity (1.42 [95% CI, 1.19-1.71] for NP, 2.19 [95% CI, 1.88-2.54] for PDWA, and 3.91 [95% CI, 2.97-5.14] for AH), comparable to surgical cohorts with BBD. Risk also increased with increasing lesion multiplicity (SIR: 2.40 [95% CI, 2.06-2.79] for ≥3 foci of NP, 3.72 [95% CI, 2.31-5.99] for ≥3 foci of PDWA, and 5.29 [95% CI, 3.37-8.29] for ≥3 foci of AH). Ten-year BC cumulative incidence was 4.3% for NP, 6.6% for PDWA, and 14.6% for AH vs an expected population cumulative incidence of 2.9%. Conclusions and Relevance: In this contemporary cohort study of women diagnosed with BBD in the percutaneous biopsy era, overall risk of BC was increased vs the general population (DCIS and invasive cancer combined), similar to that in historical BBD cohorts. Development and validation of pathologic classifications including both BBD severity and multiplicity may enable improved BC risk stratification.

BACKGROUND: Recent studies have shown that breast arterial calcification (BAC) detected on screening mammography is linked to cardiovascular diseases via medial calcification. However, its effect on cardiovascular outcomes remains unclear. Therefore, we conducted a meta-analysis to determine the effect of BAC on cardiovascular outcomes in patients. METHODS: Three electronic databases (Pubmed, Embase, and Scopus) were searched on May 1, 2022, for studies examining the relationship between BAC and cardiovascular outcomes including cardiac death, acute myocardial infarction, ischemic heart disease, stroke, peripheral artery disease, and heart failure. A random-effects meta-analysis model was used to summarise the studies. RESULTS: A total of 5 longitudinal studies were included with a combined cohort of 87,865 patients. Significantly, the pooled risk ratio (RR) of the association between BAC and cardiac death was 2.06 (P < 0.00001). BAC was associated with a significantly increased risk of developing other cardiovascular diseases, such as ischemic/hemorrhagic stroke (RR 1.51; P = 0.003), ischemic stroke (RR 1.82; P < 0.00001), peripheral vascular disease (RR 1.24; P = 0.003), and heart failure (RR 1.84; P < 0.00001). There was no significant relationship for developing myocardial infarction or for total cardiovascular diseases. CONCLUSIONS: Our findings suggest that BAC was associated with an increased risk of cardiovascular mortality, and certain cardiovascular outcomes. There is thus a potential to use BAC as a sex-specific cardiovascular risk assessment tool. Furthermore, there is a need for more widespread reporting of BAC to better understand the pathophysiologic mechanisms behind its correlation with cardiovascular disease and to apply it in clinical practice.

Breast abscesses are still a common cause of morbidity among lactational females. Over the years, there has been an increase in the incidence of non-lactational breast abscesses and a decrease in lactational breast abscesses. The management could be the use of the conventional method of surgical incision and drainage or the newer techniques of needle aspiration or suction drain or catheter in addition to the administration of antibiotics. The use of needle aspiration as the minimal-invasive conservative technique is generally recommended for abscesses less than 3-5 cm in diameter. However, recent studies have compared the two methods for abscesses larger than 3 cm and among patients with risk factors for breast abscesses. We aim to present the clinical evidence showing the comparison between needle aspiration and incision and drainage for breast abscesses irrespective of the size of the abscesses. There is a lack of comparative information on the two treatment modalities for breast abscesses larger than 3 cm in diameter; however, needle aspiration is being tried because of its advantages like cosmetic preference, short hospital stay and healing time, and no stoppage of breastfeeding.

Cardiovascular diseases (CVD), including coronary artery disease (CAD), continue to be the leading cause of global mortality among women. While traditional CVD/CAD prevention tools play a significant role in reducing morbidity and mortality among both men and women, current tools for preventing CVD/CAD rely on traditional risk factor-based algorithms that often underestimate CVD/CAD risk in women compared with men. In recent years, some studies have suggested that breast arterial calcifications (BAC), which are benign calcifications seen in mammograms, may be linked to CVD/CAD. Considering that millions of women older than 40 years undergo annual screening mammography for breast cancer as a regular activity, innovative risk prediction factors for CVD/CAD involving mammographic data could offer a gender-specific and convenient solution. Such factors that may be independent of, or complementary to, current risk models without extra cost or radiation exposure are worthy of detailed investigation. This review aims to discuss relevant studies examining the association between BAC and CVD/CAD and highlights some of the issues related to previous studies' design such as sample size, population types, method of assessing BAC and CVD/CAD, definition of cardiovascular events, and other confounding factors. The work may also offer insights for future CVD risk prediction research directions using routine mammograms and radiomic features other than BAC such as breast density and macrocalcifications.

ABSTRACT: Nonsteroidal anti-inflammatory agents (NSAID) are associated with modest inconsistent reductions in breast cancer risk in population-based cohorts, whereas two focused studies of patients with benign breast disease (BBD) have found lower risk with NSAID use. Given that BBD includes fibroinflammatory lesions linked to elevated breast cancer risk, we assessed whether NSAID use was associated with lower breast cancer risk among patients with BBD.Participants were postmenopausal women in the Cancer Prevention Study-II (CPS-II), a prospective study of cancer incidence and mortality, who completed follow-up surveys in 1997 with follow-up through June 30, 2015. History of BBD, NSAID use, and covariate data were updated biennially. This analysis included 23,615 patients with BBD and 36,751 patients with non-BBD, including 3,896 incident breast cancers over an average of 12.72 years of follow-up among participants. NSAID use, overall and by formulation, recency, duration, and pills per month was analyzed versus breast cancer risk overall and by BBD status using multivariable-adjusted Cox models; BBD status and NSAID use were modeled as time-dependent exposures.Patients with BBD who reported using NSAIDs experienced lower breast cancer risk (HR, 0.87; 95% CI, 0.78-0.97), with similar effects for estrogen receptor (ER)-positive breast cancers [HR, 0.85; 95% confidence interval (CI), 0.74-0.97] and ER-negative breast cancers (HR, 0.87; 95% CI, 0.59-1.29); among women without BBD, NSAID use was unrelated to risk (HR, 1.02; 95% CI, 0.92-1.13; Pinteraction = 0.04). Associations stratified by age, obesity, menopausal hormone use, and cardiovascular disease were similar.Among patients with BBD, NSAID use appears linked to lower breast cancer risk. Further studies to assess the value of NSAID use among patients with BBD are warranted. PREVENTION RELEVANCE: We examined whether NSAID use, a modifiable exposure, is associated with breast cancer risk in postmenopausal women from the Cancer Prevention Study-II with self-reported benign breast disease, an often inflammatory condition associated with higher rates of breast cancer.

Breast density (BD) and breast arterial calcifications (BAC) can expand the role of mammography. In premenopause, BD is related to body fat composition: breast adipose tissue and total volume are potential indicators of fat storage in visceral depots, associated with higher risk of cardiovascular disease (CVD). Women with fatty breast have an increased likelihood of hypercholesterolemia. Women without cardiometabolic diseases with higher BD have a lower risk of diabetes mellitus, hypertension, chest pain, and peripheral vascular disease, while those with lower BD are at increased risk of cardiometabolic diseases. BAC, the expression of Monckeberg sclerosis, are associated with CVD risk. Their prevalence, 13 % overall, rises after menopause and is reduced in women aged over 65 receiving hormonal replacement therapy. Due to their distinct pathogenesis, BAC are associated with hypertension but not with other cardiovascular risk factors. Women with BAC have an increased risk of acute myocardial infarction, ischemic stroke, and CVD death; furthermore, moderate to severe BAC load is associated with coronary artery disease. The clinical use of BAC assessment is limited by their time-consuming manual/visual quantification, an issue possibly solved by artificial intelligence-based approaches addressing BAC complex topology as well as their large spectrum of extent and x-ray attenuations. A link between BD, BAC, and osteoporosis has been reported, but data are still inconclusive. Systematic, standardised reporting of BD and BAC should be encouraged.

BACKGROUND: Atherosclerotic cardiovascular disease is still the leading cause of mortality for women. Breast cancer screening with mammography is recommended in all women aged over 40 years. AIMS: Whether breast artery calcification (BAC) is associated with cardiovascular disease is not clear. We aimed to evaluate the association between BAC and the presence of coronary atherosclerosis determined by CT. METHODS: All patients who underwent both mammography and coronary CT angiography between January 2010 and December 2016 were screened, and patients with a duration of less than 12 months between CT and mammography were included. RESULTS: A total of 320 women were included and BAC was detected in 47 (14.6%) patients. BAC was correlated with age and CT coronary calcium score. Both the frequency of critical coronary artery stenosis (34% vs 10.6%; p = 0.001) and CT coronary calcium score (5.5 vs 0; p = 0.001) was significantly higher in patients with BAC. The absence of BAC was a strong predictor of the absence of significant coronary artery disease (p = 0.001). BAC was independently associated with all-cause mortality after excluding patients with breast cancer (HR: 5.32; p = 0.013). CONCLUSION: Breast artery calcification is associated with coronary calcium score and significant coronary stenosis. A high BAC score is related to increased mortality.

Introducción: Las complicaciones mamarias relacionadas con la lactancia materna suelen aparecer entre el primer y el décimo día posparto, las cuales pueden provocar lesiones en la salud de la mujer y en el destete precoz. Por lo tanto, la acción de la enfermera frente a estas condiciones es de gran importancia social. Objetivo: Comprender la actuación de enfermería ante complicaciones mamarias relacionadas con la lactancia materna. Métodos: Estudio descriptivo con enfoque cualitativo basado en la Teoría de las Representaciones Sociales, realizado con 17 enfermeras que trabajan en las 29 Unidades de Salud de la Familia del municipio de Porto Seguro, Bahía, Brasil, en el período de febrero a junio de 2021. Como técnica de recolección de datos, se utilizó la entrevista guiada por un guion semiestructurado. Los datos empíricos se analizaron mediante el análisis de contenido temático propuesto por Bardin. Resultados: Los resultados obtenidos tras el análisis fueron interpretados y apoyados en la Teoría de las Representaciones Sociales, que permitió la construcción de la categoría: Praxis de las enfermeras frente a las complicaciones mamarias. La categoría demostró que el conocimiento de las enfermeras sobre las complicaciones mamarias es insuficiente para anclar la práctica del cuidado. Conclusión: El conocimiento de las enfermeras sobre las complicaciones mamarias relacionadas con la lactancia materna demostró ser insuficiente para ofrecer prácticas asistenciales eficaces y actualizadas, necesarias para una actuación adecuada y que favorezcan el mantenimiento de la lactancia materna durante el tratamiento, por lo que se requiere educación permanente sobre el tema.
Introduction: Breast complications related to breastfeeding usually appear between the first and tenth postpartum day. They may appear with lesions to women's health and early weaning. Therefore, the nurse's action in the face of these conditions is of great social importance. Objective: To understand the nursing action in the face of breast complications related to breastfeeding. Methods: A descriptive study with a qualitative approach and based on the social representations theory was conducted with 17 nurses working in the 29 family health units of Porto Seguro Municipality, Bahia State, Brazil, in the period from February to June 2021. The used data collection technique was the interview guided by a semistructured script. The empirical data were analyzed using the thematic content analysis proposed by Bardin. Results: The results obtained after the analysis were interpreted and supported by the social representations theory, which allowed the construction of the category praxis of nurses in the face of breast complications. The category showed that the nurses' knowledge about breast complications is insufficient to anchor the practice of care. Conclusion: The nurses' knowledge about breast complications related to breastfeeding proved to be inept to offer effective and updated care practices, necessary for an adequate performance and favoring the maintenance of breastfeeding during treatment; therefore, permanent education on the subject is required.

BACKGROUND: Recreational physical activity (PA) has been shown to be inversely associated with breast cancer risk. However, the association of recreational PA with benign proliferative epithelial disorders (BPED) of the breast, conditions associated with increased risk of breast cancer, has not been adequately studied. METHODS: We used data from an ancillary study of benign breast disease conducted among the 68 132 postmenopausal women (aged 50-79 at recruitment) participating in the Women's Health Initiative randomized clinical trials. All clinical trial participants underwent annual or biennial mammogram screening. During the follow-up, for women who reported breast biopsies but were cancer free, the associated histological sections were obtained and subjected to standardized central pathology review. Self-reported recreational PA at baseline (n = 61 684) and at 3 years of the follow-up (n = 55 923) were quantified as metabolic equivalents [MET]-h/week. There were 1624 confirmed BPED cases during an average follow-up time of 7.7 years. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: Higher average PA over 4 years was associated with lower risk of non-atypical BPED (P-trend = 0.02). There was a 6% lower risk of non-atypical BPED for every 5 MET-h/week increase between baseline and year 3 (HR = 0.94, 95% CI 0.89-0.99). Compared with women who remained inactive (PAbaseline and PAyear3 <9 MET-h/week), those who became active (PAbaseline<9 MET-h/week to PAyear3 ≥9 MET-h/weekee), remained active (PAbaseline and PAyear3 ≥9 MET-h/week), or decreased activity (PAbaseline ≥9 MET-h/week to PAyear3 <9 MET-h/week) had lower BPED risk. CONCLUSIONS: Recreational physical activity after menopause was associated with lower BPED risk among postmenopausal women.

BACKGROUND: Milk fistula is a potential complication of radiologic and surgical procedures on the lactating breast, though its incidence is unknown. Some postulate that larger defects and/or closer proximity to the nipple increase the risk of fistula. OBJECTIVE: This study aimed to estimate the incidence of milk fistula and characterize risk factors in patients who continued breastfeeding after surgical or radiological procedures. METHODS: A retrospective cohort analysis of pregnant or lactating women treated at a multidisciplinary breast clinic from July 2016 through August 2019 was performed. Demographic and clinical variables were analyzed using ANOVA and Pearson's Chi-square. RESULTS: Two pregnant and 43 lactating patients underwent 71 interventions. The incidence of milk fistula within one week of intervention was 1.4%. One fistula was diagnosed six days after retroareolar abscess drainage. The fistula closed successfully with continued breastfeeding. When categorized by the caliber of the most invasive intervention (large-caliber: mass excision, n = 7; medium-caliber: percutaneous drain insertion, n = 18; small-caliber: stab incision, aspiration, core needle biopsy, n = 20), patients were similar in age, race/ethnicity, weeks postpartum, and frequency of central versus peripheral interventions. The low incidence of fistula prevented quantitative evaluation of potential risk factors. CONCLUSIONS: Milk fistula is a rare occurrence following radiologic or surgical breast interventions performed during pregnancy or lactation. Indicated procedures should not be deferred, but periareolar approaches should be avoided when possible. Cessation of lactation is not mandatory for fistula closure, and continued breastfeeding should be recommended.

BACKGROUND: It is well established that tumors are antigenic and can induce an immune response by the host, entailing lymphocytic infiltration of the tumor and surrounding stroma. The extent and composition of the immune response to the tumor, assessed through evaluation of tumor-infiltrating lymphocyte counts, has been shown in many studies to have prognostic and predictive value for invasive breast cancer, but currently, there is little evidence regarding the association between infiltrating immune cell counts (IICCs) in women with benign breast disease (BBD) and risk of subsequent invasive breast cancer. METHODS: Using a cohort of 15,395 women biopsied for BBD at Kaiser Permanente Northwest, we conducted a nested case-control study in which cases were women who developed a subsequent invasive breast cancer during follow-up and controls were individually matched to cases on age at BBD diagnosis. We assessed IICCs in normal tissue and in the BBD lesions, and we used unconditional logistic regression to estimate the multivariable odds ratios (OR) and 95% confidence intervals (CI) for the associations between IICCs and breast cancer risk. RESULTS: There was no association between the IICC in normal tissue (multivariable OR per 5% increase in IICC = 1.05, 95% CI = 0.96-1.16) or in the BBD lesion (OR per 5% increase in IICC = 1.06, 95% CI = 0.96-1.18) and risk of subsequent invasive breast cancer. Also, there were no associations within subgroups defined by menopausal status, BBD histology, BMI, and history of smoking. CONCLUSION: The results of this study suggest that IICCs in BBD tissue are not associated with altered risk of subsequent invasive breast cancer.

This study aimed to investigate the effect of calcifications on shear-wave elastography in evaluating breast lesions. We retrospectively reviewed ultrasound images of 673 breast lesions and compared the elasticity between lesions with and without calcifications in three subgroups: benign lesions, in situ carcinomas and invasive carcinomas. Breast lesions were confirmed histologically (nâ¯=â¯401) or by follow-up images for more than 2 y (nâ¯=â¯272). Calcifications were present in 25.3% (170/673) of the lesions. The Emean values with and without calcifications, respectively, were as follows: 62.8 and 29.8 kPa in benign lesions (pâ¯=â¯0.000), 114.6 and 52.8 kPa in in situ carcinomas (pâ¯=â¯0.037) and 171.9 and 146.4 kPa in invasive carcinomas (pâ¯=â¯0.018). The presence of calcifications significantly increased the Emean of breast lesions. Shear-wave elastography should be carefully interpreted in benign lesions with calcifications and in situ carcinomas without calcifications.

Mammary hamartoma is benign lesion and relatively rare. 17 cases of breast cancer associated with a hamartoma had been previously documented in the literature. We describe herein a case of noninvasive ductal carcinoma of the breast arising in hamartoma in a woman of 60's. The discordance of images of the mass between mammogram and ultrasonogram can lead us to detect the carcinoma within the hamartoma in our case. J. Med. Invest. 67 : 368-371, August, 2020.

BACKGROUND: There is increasing evidence that breast arterial calcification (BAC), an incidental finding on 3-29% of mammograms, could be used to screen for coronary artery disease (CAD). We conducted a systematic review to assess the associations between BAC and CAD and its risk factors (hypertension, hypercholesterolemia, diabetes mellitus and smoking). METHODS AND FINDINGS: MEDLINE and EMBASE databases and references of relevant papers were searched up to 18 February 2020 for English language studies that evaluated the associations of BAC and CAD and its risk factors. A single reviewer extracted all data and assessed study quality with verification by another independent reviewer, if required. Across 31 studies (n = 35,583; 3 longitudinal and 28 cross-sectional studies) that examined the association of BAC and CAD, the OR was 2.61 (95% CI 2.12-3.21; I2 = 71%). Sub-analysis of studies that graded BAC severity using the 4- (4 studies) or 12-point scale systems (3 studies) revealed an association with CAD and moderate-severe BAC (OR 4.83 (95%CI 1.50-15.54) and OR 2.95 (95%CI 1.49-5.84), respectively) but not mild BAC (OR 2.04 (95%CI 0.82-5.05) and OR 1.08 (95%CI 0.42-2.75), respectively). BAC was associated with hypertension (42 studies; n = 32,646; OR 1.80; 95% CI 1.47-2.21; I2 = 85%) and diabetes mellitus (51 studies; n = 53,464; OR 2.17; 95% CI 1.82-2.59; I2 = 75%) but not with hypercholesterolemia (OR 1.31; 95%CI 0.97-1.77; I2 = 67%). Smoking was inversely associated with BAC (35 studies; n = 40,002; OR 0.54; 95% CI 0.42-0.70; I2 = 83%). Studies mostly included symptomatic women. Marked heterogeneity existed and publication bias may be present. CONCLUSIONS: BAC is associated with CAD, diabetes mellitus and hypertension and inversely associated with smoking. Whether BAC could screen for CAD cannot be determined from current published data due to the lack of larger prospective studies. A consensus approach to quantifying BAC may also facilitate further translation into clinical care. PROSPERO: CRD42020141644.

We describe the case of a 41-year-old woman with primary Sjögren's syndrome (SS) who presented multiple recurrences of breast amyloidosis. Each recurrence of breast amyloidosis showed different sonographic features, potentially mimicking malignancy. We briefly discuss the possible cause of this variability in imaging features based on the radiologic-histologic correlation.

Currently, the epidemic of 2019 coronavirus disease (COVID-19) is still ongoing. Its characteristics include high contagiousness, herd susceptibility and clinical phenotype diversity, which have a severe influence on people's daily life and rountine therapy for other diseases. Breast dieases are clinical common diseases. In the central epidemic area of COVID-19, the clinical specialists of breast diseases should consider all of the following factors comprehensively: the prevention of COVID-19, the diagnosis and treatment of breast diseases and the accessibility of medical resources. Besides, we should select the appropriate therapy and optimize treatment process so as to prevent the propagation and cross infection of COVID-19 as well as manage the breast diseases without delay. Therefore, we carried out some management proposals of the patients with breast diseases in the central epidemic area during the epidemic of COVID-19 on the basis of conventional treatment guidelines and clinical experiences. The suggestions and corrections from colleagues will be welcomed.
