    Abstract Granulomatous inflammation is an uncommon inflammatory condition of the breast that includes both infectious (bacterial, fungal, parasitic) and noninfectious (autoimmune, sarcoidosis, idiopathic granulomatous mastitis [IGM], reaction to foreign materials) etiologies. IGM is the most common subset of granulomatous inflammation where no underlying etiology is established. Infectious causes of granulomatous inflammation should be excluded, as these have established treatments that can significantly improve patient outcomes. IGM should be considered in the differential when mastitis is refractory to antibiotics. Patients usually present with an erythematous, tender, palpable unilateral breast mass. The most common mammographic presentation is a focal or global asymmetry. The imaging appearance mimics breast cancer, therefore diagnosis usually requires tissue sampling with histopathologic analysis and cultures to exclude infection. When patients are diagnosed with IGM, this poses a clinical dilemma as there are a variety of treatment options available, including oral and intralesional steroids. The time course of the disease is often prolonged by multiple recurrences, and specific treatment remains an area of ongoing research. The purpose of this article is to review the range of clinical features, imaging manifestations, associated histopathology, and management of IGM.

    Abstract Lactating adenomas are benign breast lesions that occur in pregnant, lactating, and postpartum women. These lesions have no associated malignant potential; their origin is disputed with no consensus on whether they represent hyperplastic or neoplastic processes. On ultrasound, lactating adenomas are classically described as solid, circumscribed, parallel masses with iso/hypoechoic internal echotexture and posterior enhancement. Histologically, lactating adenomas appear as circumscribed nodules of tightly packed lobular acini with extensive lactational change during pregnancy or the postpartum period. Masses in pregnant and lactating women with probably benign imaging characteristics-oval, circumscribed, parallel, iso/hypoechoic-can be managed with short interval follow-up (BI-RADS 3) rather than biopsy. However, lactating adenomas can also demonstrate characteristics that overlap with pregnancy-associated breast cancer, such as margins that are not circumscribed, prompting biopsy to exclude pregnancy-associated carcinoma. Breast imaging radiologists must be aware of the variable appearances of lactating adenomas to appropriately manage pregnant and lactating women presenting with palpable lumps.

    Abstract Objectives: The coronavirus disease 2019 pandemic has halted in-person medical student education in many large academic centers, including the University of Washington. We identified a unique opportunity to bring comprehensive and targeted anatomic pathology training to large numbers of medical students who would not receive it otherwise but also need credited coursework.
    Methods: We developed a comprehensive 2-week remote-learning course encompassing lectures, virtual slides, discussion groups, and unique case-based activities. Activities are tailored to the nonpathologist future clinician, emphasizing basic microscopy and pathology terminology. We employ multiple strategies and technologies to increase engagement while distance learning, including screen annotation, "flipped classroom" slide presentations, and repetition of common themes.
    Results: Given 13 virtual courses to choose between 13% of students enrolled in our course (70 of our 540 rising third- and fourth-year students), a nearly 10-fold increase in average pathology rotators.
    Conclusions: This is an unprecedented opportunity to provide tailored anatomic pathology instruction, both helping our medical students continue training during crisis and illuminating the field of pathology for our future colleagues. Preliminary results have been overwhelmingly positive regarding understanding of pathology concepts as well as attitudes toward pathology.

    Abstract Introduction: We have previously found that HER2 expression is dynamic, and can change from the primary breast tumor to matched recurrences. With this work, we aimed to assess the dynamics of HER2 during neoadjuvant treatment.(NAT).
    Methods: We reviewed HER2 expression in pre- and post-treatment samples from consecutive patients with early-stage breast cancer that received NAT and underwent surgery at Dana-Farber Brigham Cancer Center between 01/2016-08/2022. The primary outcome was evolution of HER2 expression from pre- to post-NAT specimens in patients with residual disease.
    Results: Among 1613 patients receiving NAT, 1080 had residual disease at surgery. A total of 319 patients (29.5%) experienced a change in HER2 expression (HER2 0 vs. HER2-low vs. HER2-positive) from the pre-treatment sample to residual disease, with roughly equal distribution between decreased (50.5%) and increased HER2 expression (49.5%). Similar rates of change in HER2 expression were observed with anthracycline-based (31.8%) or taxane/platinum-based regimens (32.4%). Patients with HER2-0 or HER2-low tumors at diagnosis were likelier to experience a change in HER2 expression post-NAT compared to HER2-positive (32.3% vs. 21.3%, p < 0.001). Changes in HER2 expression post-NAT were prognostic among patients with HER2-positive tumors at diagnosis (3-year recurrence-free survival for change vs. no change: 71.6% vs. 89.6%, p = 0.006) but not among those with HER2-negative tumors at diagnosis (3-year recurrence-free survival for change vs. no change: 79.3% vs. 81.1%, p = 0.31).
    Conclusions: Nearly 30% of patients with early-stage breast cancer showed a change in HER2 expression after NAT. Changes in HER2 expression post-NAT were only prognostic in the setting of HER2-positive tumors becoming HER2-negative at surgery.

    Abstract Purpose: New federal legislation in the United States grants patients expanded access to their medical records, making it critical that medical records information is understandable to patients. Provision of informational summaries significantly increase patient perceptions of patient-centered care and reduce feelings of uncertainty, yet their use for cancer pathology is limited.
    Methods: Our team developed and piloted patient-centered versions of pathology reports (PCPRs) for four cancer organ sites: prostate, bladder, breast, and colorectal polyp. The objective of this analysis was to identify common barriers and facilitators to support dissemination of PCPRs in care delivery settings. We analyzed quantitative and qualitative data from pilot PCPR implementations, guided by the RE-AIM framework to explore constructs of reach, effectiveness, adoption, implementation, and maintenance.
    Results: We present two case studies of PCPR implementation - breast cancer and colorectal polyps-that showcase diverse workflows for pathology reporting. Cross-pilot learnings emphasize the potential for PCPRs to improve patient satisfaction, knowledge, quality of shared decision-making activities, yet several barriers to dissemination exist.
    Conclusion: While there is promise in expanding patient-centered cancer communication tools, more work is needed to expand the technological capacity for PCPRs and connect PCPRs to opportunities to reduce costs, improve quality, and reduce waste in care delivery systems.

    Abstract Following the survival benefit demonstrated in the OlympiA trial, one year of adjuvant olaparib is now recommended for all patients with germline BRCA1/2 pathogenic/likely pathogenic variants (PV) and high-risk, HER2-negative early breast cancer after chemotherapy. However, optimal identification of high-risk patients who may derive benefit from this genomically-directed therapy is debated. In this study, we sought to characterize the real-world proportion of gBRCA1/2 PV carriers eligible for adjuvant olaparib according to the OlympiA criteria, and to compare clinicopathologic characteristics and outcomes between eligible and ineligible patients.

    Abstract Cervical mesonephric adenocarcinoma is a rare histologic cervical carcinoma variant arising from remnants of the mesonephric duct. Few clinical cases have been reported in the literature, and given the low rate of occurrence, the optimal management strategy is unknown. Most reported cases involve patients with either early stage (FIGO I) or metastatic disease. Herein, we report the only known case of locally advanced, node-positive cervical mesonephric carcinoma in a 55-year old woman with Mullerian duct anomaly of the uterus, obstructed hemivagina, and ipsilateral renal agenesis. To our knowledge, this would be the first case report with the concurrence of both rare entities. We review the treatment paradigm in this patient, and the literature, including radiotherapy and brachytherapy techniques.

    Abstract Background: Atypical lobular hyperplasia (ALH) and classic lobular carcinoma in situ encompass a spectrum of proliferative lesions known as lobular neoplasia (LN). When imaging-concordant and found in isolation on core needle biopsy (CNB), LN infrequently upgrades to carcinoma on surgical excision, and routine excision is not indicated. Upgrade rates in the setting of synchronous carcinoma are not well studied.
    Patients and methods: Patients with radiology-pathology concordant synchronous LN and separately biopsied ipsilateral (n = 35) or contralateral (n = 15) carcinoma who underwent excision between 2010 and 2021 were retrospectively identified. Frequency of upgrade, to either invasive or in situ carcinoma, was quantified, and factors associated with upgrade were assessed using Fisher's exact test.
    Results: The median age was 55 (range 33-74) years. The upgrade rate of LN was 6% and not significantly different between ipsilateral (2.9%) and contralateral (13.3%) carcinoma (p = 0.15). All upgraded LN lesions were ALH on CNB and detected as non-mass enhancement on magnetic resonance imaging (MRI). No additional disease was demonstrated after excision at the site of the original LN CNB in 22.9% (8 out of 35) of ipsilateral and 13.3% (2 out of 15) of contralateral patients. Upgrade was not associated with family history, menopausal status, imaging modality used to detect LN, or extent of LN on CNB (p > 0.05).
    Conclusions: Our results demonstrate a low upgrade rate (6%) in our study cohort of LN with synchronous ipsilateral or contralateral carcinoma, which suggests that not all LN mandates excision with synchronous carcinoma. Larger, multi-institution studies are needed to validate these findings.

    Abstract Pestis secunda (1356-1366 CE) is the first of a series of plague outbreaks in Europe that followed the Black Death (1346-1353 CE). Collectively this period is called the Second Pandemic. From a genomic perspective, the majority of post-Black Death strains of Yersinia pestis thus far identified in Europe display diversity accumulated over a period of centuries that form a terminal sub-branch of the Y. pestis phylogeny. It has been debated if these strains arose from local evolution of Y. pestis or if the disease was repeatedly reintroduced from an external source. Plague lineages descended from the pestis secunda, however, are thought to have persisted in non-human reservoirs outside Europe, where they eventually gave rise to the Third Pandemic (19th and 20th centuries). Resolution of competing hypotheses on the origins of the many post-Black Death outbreaks has been hindered in part by the low representation of Y. pestis genomes in archaeological specimens, especially for the pestis secunda. Here we report on five individuals from Germany that were infected with lineages of plague associated with the pestis secunda. For the two genomes of high coverage, one groups within the known diversity of genotypes associated with the pestis secunda, while the second carries an ancestral genotype that places it earlier. Through consideration of historical sources that explore first documentation of the pandemic in today's Central Germany, we argue that these data provide robust evidence to support a post-Black Death evolution of the pathogen within Europe rather than a re-introduction from outside. Additionally, we demonstrate retrievability of Y. pestis DNA in post-cranial remains and highlight the importance of hypothesis-free pathogen screening approaches in evaluations of archaeological samples.
