Abstract
Previously reported upgrade rates for benign breast intraductal papilloma (IDP) are widely variable. However, many previous studies have failed to consider radiologic-pathologic discordance of lesions. This review aims to synthesize malignant upgrade data for benign, concordant IDP at surgical excision. Thirteen studies were included in our meta-analysis. The pooled estimate for percentage underestimation of carcinoma was 1.4% (95% CI: 0.8%-2.0%). We conclude that these lesions can be safely managed by active surveillance.

Abstract
Currently, the optimal treatment approach for breast benign intraductal papilloma (IDP) diagnosed via biopsy remains uncertain. There is ongoing debate regarding the feasibility of clinical follow-up and the criteria for selective surgical excision. This study aims to conduct a meta-analysis to determine the rate of upgrade from breast benign IDP and identify predictive factors associated with the conversion of benign IDP to high-risk lesions or carcinoma, which could guide healthcare practitioners in selecting the appropriate clinical treatment strategy. We conducted a comprehensive search across multiple databases (PubMed, Web Of Science, Cochrane Library, and Embase) for studies published between 2012 and 2023 that evaluated upgrade rates and predictive factors of breast benign IDP diagnosed via biopsy. In addition, we included studies that reported on the clinical follow-up of patients with breast benign IDP. In total, 32 studies comprising 7371 cases of biopsy-diagnosed breast benign IDP were included. Among these cases, 720 demonstrated an upgrade to high-risk lesions or carcinoma, resulting in an upgrade rate of 6.94% [95% confidence interval (CI): 3.0-8.0%]. A subgroup of 1713 patients was clinically followed up, demonstrating an average follow-up duration of 30.95 months. Among them, 26 cases experienced an upgrade to high-risk lesions or carcinoma, yielding an upgrade rate of 1.51% (95% CI 0.00-2.00). Furthermore, we identified nine predictive factors associated with the upgrading of breast benign IDP, which included age at diagnosis, personal history of breast cancer, family history of breast cancer, multiple IDPs, lesion size ≥ 10 mm, palpable mass, calcification, and the presence of mass and asymmetry in mammographic findings. Although the conversion rate of breast benign IDP to high-risk lesions or carcinoma is relatively low, timely identification of predictive factors associated with benign IDP upgrades may help selecting the optimal clinical treatment strategy, such as surgery for patients with benign IDP presenting one or more predictive factors, while clinical follow-up for those without specific risk factors.

Abstract
Background: Papillary lesions of the breast are a heterogeneous group, encompassing a wide range of lesions. The histologic distinction between papillary breast lesions remains challenging, especially on core biopsy specimens. Aim: This study aimed to determine the rate of upgrade to atypia or malignancy of biopsy-proven papillary lesions on surgical follow-up and to assess for factors associated with an upgrade in Greater Vancouver, BC, Canada. Materials and Methods: This is a retrospective population-based study of all breast papillary lesions diagnosed on core biopsy between 2017 and 2019 in the Fraser Health Authority in Greater Vancouver, Canada. Patients were retrieved from the laboratory information system. Patient demographics, histopathologic, and radiologic findings were analyzed. Results: A total of 269 specimens from 269 patients (mean 61.1 years), including 265 female and 4 male patients, were included in the study. Of the 269 specimens, 129 (48%) were intraductal papillomas and 140 (52%) were atypical papillary lesions. The overall upgrade rate among papillomas was 11.6% (15 of 129) on final excision. The mean age of patients diagnosed with papilloma on core biopsy was significantly younger than those with atypical papillary lesions (55.6 vs 66.1 years, P < .0001). Lesion size in patients with papillomas on core biopsy was significantly smaller than those with atypical papillary lesions (11.1 vs 15.1 mm, P = .001). The upgrade rates in patients <55 and ≥55 years were 4.9% and 13.2%. Size (P = .004) and atypia on core biopsy (P = .009) were significantly associated with upgrade. Older age (>55 years) (OR = 5.3, 95% CI: 1.04-27.08) was an independent predictor of upgrade among papillomas. Size, location, and Breast Imaging-Reporting and Data System (BI-RADS) radiologic categories in our study were not associated with predicting the upgrade of papillomas. Conclusion: Our data suggest that the risk of upgrade to atypia or malignancy is sufficient to warrant the excision of benign papillomas of any size in patients aged ≥55 years. In patients younger than 55 years, observation with close clinical and radiological follow-up without surgery may be sufficient. Our findings also support surgical excision of papillomas diagnosed on core biopsy when associated with atypia.

Abstract
BACKGROUND Ductal lesions are an important, often overlooked, and poorly understood issue in breast imaging, which have a risk of underlying malignancy ranging from 5 to 23%. Ultrasonography (US), which has largely replaced galactography or ductography, has become an important imaging method to assess patients with ductal lesions. However, it is difficult to distinguish benign from malignant ductal abnormalities only by ultrasonography, most of which are recommended to be at least in subcategory 4A; these require biopsy according to the ACR BI-RADS®atlas 5th Edition-breast ultrasound. Contrast-enhanced ultrasound (CEUS) has been shown to be valuable for differentiating benign from malignant tumors, but its value is unclear in breast ductal lesions. Therefore, the purposes of this study were to explore the characteristics of malignant ductal abnormalities on US and CEUS imaging and the diagnostic value of CEUS in breast ductal abnormalities. METHODS Overall, 82 patients with 82 suspicious ductal lesions were recruited for this prospective study. They were divided into benign and malignant groups according to the pathological results. Morphologic features and quantitative parameters of US and CEUS were analyzed by comparison and multivariate logistic regression to determine the independent risk factors. The diagnostic performance was assessed by receiver operating characteristic (ROC) curve analysis. RESULTS Shape, margin, inner echo, size, microcalcification and blood flow classification on US, wash-in time, enhancement intensity, enhancement mode, enhancement scope, blood perfusion defects, peripheral high enhancement and boundary on CEUS were identified as features correlated with malignant ductal lesions. However, multivariate logistic regression showed that only microcalcification (OR = 8.96, P = 0.047) and enhancement scope (enlarged, OR = 27.42, P = 0.018) were independent risk factors for predicting malignant ductal lesions. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy and area under the ROC curve of microcalcifications combined with an enlarged enhancement scope were 0.895, 0.886, 0.872, 0.907, 0.890, and 0.92, respectively. CONCLUSIONS Microcalcification and enlarged enhancement scope are independent factors for predicting malignant ductal lesions. The combined diagnosis can greatly improve the diagnostic performance, indicating that CEUS can be useful in the differentiation of benign and malignant lesions to formulate more appropriate management for ductal lesions.

Hum Pathol 2022; 128:90-100.

Abstract
Surgical excision of breast intraductal papilloma (IDP) without atypia diagnosed on core needle biopsy (CNB) is controversial as the risk of upgrade to malignant lesions is not well established. This study investigates upgrade rates of benign and atypical IDP to ductal carcinoma in situ (DCIS) and invasive carcinoma (IC) and clinicopathologic predictors. We identified 556 cases of IDP diagnosed on CNB at a single institution from 2010-2020 after excluding patients with a history of breast carcinoma, ipsilateral high-risk lesion, radiologic/pathologic discordance, or less than 2 years of follow-up if no excision within one year. Of these, 97 biopsies were consistent with atypical IDP and 459 were benign IDP. Surgical excision was performed for 318 (57.2%), and the remaining 238 (42.8%) underwent active monitoring. The upgrade rate for IDP without atypia was 2/225 (0.9%; 1 DCIS and 1 IC). Of 93 surgically excised atypical IDPs, 19/93 (20.4%) upgraded (14 DCIS and 5 IC). Of 238 non-excised IDPs followed clinically (range 24-140 months, mean 60 months), there was no subsequent breast cancer diagnosed at the IDP site on follow-up. Mean age of patients was 56 yr±12.6sd without upgrade, 63 yr±10.6sd (p value=0.027) with DCIS, and 61 yr±10.8sd (p value=0.35) with IC. Atypical IDP was more likely to upgrade if biopsied by stereotactic guidance (8/19, 42.1% p=0.035). At our institution, we had an exceedingly low upgrade rate for benign IDP. Overall, patients with upgrade to DCIS were older. For atypical IDP, upgrade was seen in higher proportions of stereotactic biopsies.

Abstract
RATIONALE AND OBJECTIVE To determine the diagnostic yield of various imaging tests used to evaluate nipple discharge. MATERIALS AND METHODS A single institution, IRB-approved, retrospective study was performed of 320 consecutive patients presenting with nipple discharge. Imaging and pathology were reviewed to determine the yield for malignancy, atypical high-risk lesions (HRLs), and intraductal papillomas (IDPs). RESULTS Of the 320 patients, pathology or follow up confirmed 40 breast malignancies (40/320, 12.5%),14 atypical HRLs (14/320, 4.4%), 71 IDPs (71/320, 22.2%), 48 other benign pathologies (48/320,15.0%), and 147 unknown but benign cases (147/320, 45.9%). Physiologic discharge characteristics were observed in a minority of malignant cases: nonspontaneous (4/40, 10.0%); neither bloody nor clear (4/40, 10.0%); bilateral (3/40, 7.5%). Malignancy was associated with older age (p < 0.001) and bloody discharge (odds ratio 6.5, p < 0.0001). The combination of digital mammography and ultrasound had a 93% sensitivity and a 98% NPV, while contrast enhanced MRI (CE-MRI) had a 100% sensitivity and a 100% NPV for malignancy. Only three galactography examinations were performed among the malignant cohort, with minimal contribution (1 of 3) to the diagnostic evaluation. In this case, galactography findings helped determine imaging-pathology discordance, prompting a recommendation for surgical excision and subsequently a malignant diagnosis. CONCLUSION The combination of mammography and ultrasonography detected 93% of breast malignancies associated with nipple discharge and had a 98% NPV for malignancy. The value of CE-MRI is its ability to detect the remaining malignancies, not detected on mammography or ultrasound, and its ability to obviate the need for surgical duct excision.

Abstract
PURPOSE To assess the percentage of papillomas from all biopsies performed, comparing differences in patient age and race at a single institution. To assess trends in biopsied papillomas at institutions throughout the United States (US). METHODS This is a HIPPA-compliant IRB-approved single-institution (Southern1) retrospective review to assess race and age of all-modality-biopsied non-malignant papillomas as a percentage of all biopsies (percentage papillomas calculated as papilloma biopsies/all biopsies) from January 2012 to December 2019. To assess national variation, several academic or large referral centers were contacted to provide data regarding papilloma percentages, biopsy modalities, and trends in case numbers. Trends were estimated using the method of analysis of variance (ANOVA). Comparisons of differences in trends were assessed. RESULTS Southern1 institution demonstrated a significant association between race and percentage of papillomas (p < 0.0001). After adjustment for multiple comparisons with Bonferroni correction at 5% type I family error, the percentage of biopsied papillomas in Black and Asian patients remained significantly higher than in White patients (p < 0.0001 and p = 0.0032, respectively) using a Chi-square test. The regional variation in percentage of papillomas was found to be 3-9%. Southern1 institution showed a 7-year significant trend of increase in percentage of papillomas. Other institutions showed a decreasing trend (p < 0.05). CONCLUSION Black and Asian women had significantly higher papilloma percentages compared to white patients in our single institution review. This institution also showed a statistically significant trend of increasing percentage papillomas from 2012 to 2019. Multi-institutional survey found regional variation in percentage papillomas, ranging from 3% to 9%.

Abstract
Papillary lesions of the breast represent a heterogeneous group of lesions including benign papillomas, papillomas with focal epithelial atypia, fully fledged ductal carcinoma in situ (DCIS) or lobular neoplasia, papillary DCIS, encapsulated papillary carcinomas without or with invasion, solid papillary carcinomas, and invasive papillary carcinomas. A micropapillary pattern characterized by lack of fibrous stalks within the papillae is observed in micropapillary DCIS and invasive micropapillary carcinoma. In addition, a variety of other rare breast lesions reveals a papillary architecture such as tall cell carcinoma with reversed polarity (TCCRP) and mucinous cystadenocarcinoma, adenomyoepithelioma, and secretory carcinoma. In addition, benign lesions such as usual ductal hyperplasia, apocrine metaplasia, gynecomastia, and juvenile papillomatosis may show a papillary or micropapillary architecture. Fragments of a benign papilloma in a breast biopsy are considered a lesion of uncertain malignant potential (B3 in the European classification) and excision is mostly recommended. Although the knowledge about molecular pathology of papillary breast lesions has increased, there is not sufficient evidence for diagnostically useful molecular features, yet. The aim of this review is to provide an update on papillary and micropapillary lesions with emphasis on problematic areas for daily diagnostic work including biopsies.
