Pleomorphic lobular carcinoma in situ (PLCIS) of the breast is a rare variant of lobular carcinoma in situ (LCIS). We reviewed 78 cases of PLCIS diagnosed at our institution from 1998 to 2012. Among all cases, 47 (60%) were associated with invasive carcinoma and/or ductal carcinoma in situ (DCIS) after final surgical excision. Of the 20 cases with PLCIS alone on core needle biopsy (CNB), 6 (30%) were upgraded to invasive carcinoma or DCIS after final surgical excision. Our findings support a recommendation for complete surgical excision of PLCIS when diagnosed on CNB...

Previous studies have demonstrated that fibulin-2 may facilitate cancer cell invasion and metastasis during tumor progression. In the present study, immunohistochemical analyses of fibulin-2 and collagen IV expression in 35 patients with breast cancer were performed to define their localization and association with breast cancer tissue. Fibulin-2 was revealed to be expressed in all tissues surrounding the breast ducts and blood vessels in normal breast tissue, while its expression was not integrated in invasive ductal carcinoma or terminal duct-lobular unit...

BACKGROUND: Roux-en-Y gastric bypass (RYGB) improves the pathophysiology that contributes to obesity-related nonalcoholic steatohepatitis (NASH). Whether obesity-related fibrosis improves is unclear. We hypothesized that RYGB reverses NASH and fibrosis, and indocyanine green (ICG) clearance provides a sensitive measure for detecting asymptomatic fatty liver disease. METHODS: One hundred six obese adults scheduled for RYGB had preoperative liver function assessed using standard tests and ICG clearance and core liver biopsies obtained during RYGB...

This study investigated the network of genes that are co-expressed with androgen receptor (AR) to discover novel AR targets in breast cancer. Bioinformatics analysis of two datasets from breast cancer cell lines resulted in the identification of an AR-gene signature constituted of 98 genes that highly correlated with AR expression. Notably, C1orf64 showed the highest positive correlation with AR across the datasets with a correlation coefficient (CC) of 0.737. In addition, C1orf64 closely correlated with AR expression in primary and metastatic breast tumors and C1orf64 expression was relatively higher in breast tumors with a lower grade and lobular histology...

Polo-like kinases 1 (PLK1), a key regulator of mitosis, plays an essential role in maintaining genomic stability. Up-regulation of PLK1 was found in tumorigenesis and tumor progression of diverse cancers. However, the clinicopathological and prognostic implications of PLK1 in breast cancer (BC) have yet to be unveiled. Therefore, using PubMed, Web of Science, Embase, and Chinese databases, we conducted a meta-analysis to define the potential clinical value of PLK1 in BC. Eleven eligible articles with 2481 patients enrolled were included in the present meta-analysis, of which eight studies reported on the relationship between PLK1 expression and clinicopathological features, and nine studies provided survival data in BC patients...

Nodular hyperplasia (NH) of the Bartholin gland is an exceedingly rare benign solid lesion of the female genital tract that can mimic the Bartholin gland cyst clinically. The histologic criteria for NH were established in 1998 by Koenig and Tavassoli. In this case series, we describe 4 cases of NH from Women and Infants Hospital in Rhode Island. All cases have microscopic features of lobular proliferation of acini and inspissated mucin. One case especially has extensive mucin extravasation mimicking an aggressive angiomyxoma...

PURPOSE: Atypical ductal and atypical lobular hyperplasia (AH) of the breast are important proliferative lesions which are associated with a significantly increased risk for breast cancer. The breast cancer which develops in association with AH may occur synchronously, representing local progression, or metachronously at a later date in either the ipsilateral or contralateral breast. These high-risk characteristics of AH suggest they contain significant genomic changes. METHODS: To define the genomic changes in AH, a comprehensive review of the literature was conducted to identify the numerical chromosomal and structural chromosomal changes, DNA methylation, and gene expression abnormalities in atypical ductal and atypical lobular hyperplasia...

We investigated the protective effect of vitamin D against liver damage caused by carbon tetrachloride (CCl4). Twenty-four male rats were divided into four equal groups: G1, untreated controls; G2, administered CCl4; G3, administered both CCl4 and vitamin D for 10 weeks; G4, administered CCl4 for 10 weeks and vitamin D for 12 weeks. At the end of experiment, intracardiac blood samples were taken and liver samples were removed. Hepatic damage due to CCl4 was assessed using biochemistry and histopathology. Glutathione (GSH) levels decreased, while malondialdehyde (MDA) levels increased in liver tissues of G2...

Populations with essential hypertension have a high risk of nonalcoholic steatohepatitis (NASH). In this study, we investigated the mechanism that underlies the progression of hypertension-associated NASH by comparing differences in the development of high fat and cholesterol (HFC) diet-induced NASH among three strains of rats, i.e., two hypertensive strains comprising spontaneously hypertensive rats and the stroke-prone spontaneously hypertensive 5/Dmcr, and the original Wistar Kyoto rats as the normotensive control...

Immunotherapies targeting cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and the programmed cell death 1 (PD-1) receptor and its ligand (PD-L1) have demonstrated substantial clinical benefit in patients with clinically advanced solid malignancies. However, autoimmune toxicities are common and often significant adverse events with these agents. While rash and pruritus remain the most common cutaneous complications in treated patients, novel dermatologic toxicities related to immune checkpoint blockade continue to emerge as the number of patients exposed to immunotherapy increases...

Mammary myofibroblastoma (MFB) is a rare mesenchymal tumor, derived from mammary stromal fibro/myofibroblasts, which has various morphological features and characteristic immunohistochemical staining. The epithelioid morphologic variant is defined, accordingly, as a proliferation of exclusively or predominantly (>50%) epithelioid cells, variably embedded in a myxoid to fibrous stroma. These histological and cytological features may pose a diagnostic challenge mainly with metaplastic carcinoma and invasive lobular carcinoma of the breast...

PURPOSE: In a pilot study, we introduce fast handheld Multi-Spectral Optoacoustic Tomography (MSOT) of the breast at 28 wavelengths, aiming to identify high-resolution optoacoustic (photoacoustic) patterns of breast cancer and non-cancerous breast tissue. EXPERIMENTAL DESIGN: We imaged 10 female patients aged 48-81 years with malignant non-specific breast cancer or invasive lobular carcinoma. Three healthy volunteers aged 31-36 years were also imaged. Fast-MSOT was based on unique single-frame-per-pulse (SFPP) image acquisition employed to improve the accuracy of spectral differentiation over using a small number of wavelengths...

AIM: Interstitial lung disease (ILD) in infants represents a rare and heterogenous group of disorders, distinct from those occurring in adults. In recent years a new entity within this category is being recognized, namely filamin A (FLNA) mutation related lung disease. Our aims are to describe the clinical and radiological course of patients with this disease entity to aid clinicians in the prognostic counseling and management of similar patients they may encounter. METHOD: A retrospective case note review was conducted of all patients treated at our institution (a specialist tertiary referral childrens' center) for genetically confirmed FLNA mutation related lung disease...

Breast cancer undergoes collective tissue invasion and, in experimental models, can collectively metastasize. The prevalence of collective invasion and its contribution to distant metastasis in clinical disease, however, remains poorly defined. We here scored the adipose tissue invasion of primary invasive ductal carcinoma (IDC), expressing E-cadherin, and E-cadherin negative invasive lobular carcinoma (ILC) and identified predominantly collective invasion patterns (86/86 samples) in both carcinoma types. Whereas collective invasion in IDC lesions retained adherens junctions, multicellular clusters and "Indian files" in ILC, despite the absence of adherens junctions (AJ) proteins E-cadherin and β-catenin, retained CD44 at cell-cell contacts...

The incidence of synchronous bilateral breast carcinomas (BBCs) has increased with a more frequent use of magnetic resonance imaging screening of the contralateral breast in women with newly diagnosed breast cancer. A total of 30% of all BBCs occur synchronously. In the present study, we describe a unique case of synchronous BBC in a 59-year-old previously healthy woman with no known family history of breast or ovarian cancer. At the time of diagnosis the patient had an invasive lobular carcinoma (ILC) in the right breast and an adenoid cystic carcinoma (ACC) in the left breast...

Extrahepatic bile duct obstruction can be caused by various pathologies, most of them being malignant. Painless, progressive jaundice is the usual mode of presentation. We report a case of distal Common Bile Duct (CBD) obstruction due to a Benign Intramural Beale gland hyperplasia mimicking a periampullary carcinoma. Peribiliary glands (Beale Glands) are a group of seromucinous glands, normally seen within the fibromuscular wall and periductal connective tissue in the extrahepatic and large intrahepatic ducts and also in the neck of the Gall bladder...

Inhibition of apoptosis signal-regulating kinase 1 (ASK1), a serine/threonine kinase, leads to improvement in inflammation and fibrosis in animal models of nonalcoholic steatohepatitis (NASH). We evaluated the safety and efficacy of selonsertib, a selective inhibitor of ASK1, alone or in combination with simtuzumab, in patients with NASH and stage 2 or 3 liver fibrosis. In this multicenter phase 2 trial, 72 patients were randomized to receive 24 weeks of open-label treatment with either 6 or 18 mg of selonsertib orally once daily with or without once-weekly injections of 125 mg of simtuzumab, or simtuzumab alone...

In a retrospective study performed in California, U.S.A., ca. 3% of patients with gastric intestinal metaplasia (GIM) developed gastric cancer (GC) within a median time period of 4.6 years after diagnosis of GIM. This observation stresses the importance of targeted surveillance even in regions with a low GC prevalence. Patients with alcoholic liver disease as well as survivors of colorectal and lobular breast cancer were found to be at increased risk of secondary GC. A population-based Chinese study confirmed "serologic biopsy" as a useful screening tool for stratifying the individual risk of developing GC...
