BACKGROUND: Reduction mammaplasty is one of the most common plastic surgery procedures. Preoperative imaging and histopathology protocols vary among countries and institutions. We aimed to analyze the incidence of occult breast cancer and high-risk lesions in reduction mammaplasty specimens. We also analyzed whether patients with abnormal histopathology differed from the study population in terms of demographics. PATIENTS AND METHODS: In total, 918 women who underwent reduction mammaplasty from January 2007 to December 2011 were retrospectively reviewed for demographics, preoperative imaging, further preoperative examinations, pathology reports, and postoperative follow-up...

Twelve lung neuroendocrine tumors with morphologic features of carcinoid tumors but with mitotic count >10/2 mm are reported. There were 7 males and 5 females, with age ranging from 56 to 78 years. Four cases were from never-smokers. All tumors showed architectural and cytomorphologic features of carcinoid tumor, including organoid nesting, insular, trabecular, or acinar growth, and tumor cells with low nucleocytoplasmic ratio, abundant cytoplasm, ovoid to round nuclei, and salt and pepper chromatin. Angulated or confluent nesting, insular or lobular growth pattern was also seen...

AIMS: Primary cilia play an important role in the regulation of cell signalling pathways and are thought to have a role in cancer but have seldom been studied in human cancer samples. METHODS: Primary cilia were visualised by dual immunofluorescence for anti-CROCC (ciliary rootlet coiled-coil) and anti-tubulin in a range of human cancers (including carcinomas of stomach, pancreas, prostate, lung and colon, lobular and ductal breast cancers and follicular lymphoma) and in matched normal tissue (stomach, pancreas, lung, large and small intestines, breast and reactive lymph nodes) samples using a tissue microarray; their frequency, association with proliferation, was measured by Ki-67 staining and their structure was analysed...

Lumpectomy with microscopically clear margins is a safe and effective approach for surgical management of breast carcinoma. Margins are positive for tumor in 18-50% of lumpectomies, as it is not possible to accurately determine the shape or microscopic borders of a tumor preoperatively or intraoperatively. We examined the 3D microanatomy and growth patterns of common breast carcinoma subtypes to provide guidance for lumpectomy surgery. Prospective consent was obtained for the use of excess tissue from patients undergoing lumpectomy or mastectomy for breast carcinoma...

BACKGROUND: Signet ring cells (SRCs) often accompany gastrointestinal carcinoma, referred to as SRC carcinoma; however, breast cancers containing SRCs have not been well characterized, leaving the prognostic significance of SRCs undetermined. We have described clinicopathological characteristics of patients with breast cancer containing SRCs in relation to the expression levels of MUC1, MUC2, MUC4, MUC5AC, and MUC6. METHODS: Twenty-two breast cancer cases with variable degrees of SRC population were retrospectively studied...

Associations between mast cell infiltration and the clinical features and known molecular profile of breast cancer remain unclear. The distribution difference of mast cell was evaluated, in 219 patients with no special type of invasive carcinoma, using sorts of age, max diameter of cancer, histological type, lymph node metastasis as well as the expressions of estrogen receptor (ER), progestogen receptor (PR), human epidermal growth factor receptor 2 (HER-2) and nuclear protein Ki67. The mast cell density (MCD) in patients younger than 50 years old was significantly higher than that in patients with age ≥ 50...

Subareolar sclerosing duct hyperplasia (SSDH) remains to be fully characterized nearly 20 years after initial description. Thirty-five SSDH cases diagnosed over a 16-year period (January 2000 to December 2015) were reviewed. All patients were female (mean age = 59 years, range = 18-80) who had presented with a unilateral solitary lesion (left 22, right 13) with a mean size of 1.3 cm (range = 0.4-3.0 cm), and showed florid and papillary epithelial hyperplasia with dense sclerosis without involvement of nipple or areolar epidermis...

Cutaneous clear cell tumors are a heterogeneous group of cutaneous neoplasms, which may show a wide range of histogenesis. We report the clinicopathological features of an agminated clear cell tumor, arising in a 67-year-old man, otherwise asymptomatic, with distinct histopathological and immunohistochemical features, which did not fit into any existing diagnostic categories. The patient presented with several skin-colored papules at the lateral and posterior aspects of the neck, which on histopathological examination showed circumscribed lobular aggregates of clear cells within the dermis...

Clinicopathologic features of breast cancer have limited accuracy to predict survival. By immunohistochemistry (IHC), Keratin 17 (K17) expression has been correlated with triple-negative status (estrogen receptor [ER]/progesterone receptor [PR]/human epidermal growth factor receptor-2 [HER2] negative) and decreased survival, but K17 mRNA expression has not been evaluated in breast cancer. K17 is a potential prognostic cancer biomarker, targeting p27, and driving cell cycle progression. This study compared K17 protein and mRNA expression to ER/PR/HER2 receptor status and event-free survival...

E-cadherin (CDH1) is a glycoprotein that mediates adhesion between epithelial cells and also suppresses cancer invasion. Mutation or deletion of the CDH1 gene has been reported in 30-60% cases of invasive lobular carcinoma (ILC). However, little is known about genomic differences between ILC with and without a CDH1 alteration. Therefore, we analyzed whole genome sequencing data of 169 ILC cases from The Cancer Genome Atlas (TCGA) to address this deficiency. Our study shows that CDH1 gene was altered in 59.2% (100/169) of ILC...

The appropriate follow-up and treatment for patients with a core biopsy diagnosis of lobular neoplasia (atypical lobular hyperplasia or lobular carcinoma in situ) remains controversial. Several studies have attempted to address this issue, with recommendations ranging from close clinical follow-up or surveillance to mandatory surgical excision in all cases. We report the findings at our institution, where virtually every core needle biopsy diagnosis of lobular neoplasia results in follow-up excision. The goal of the study was to identify potential predictors of upgrade to a more significant lesion...

The diagnostic utility of (18)F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) for breast cancer is controversial. The histological type or tumor size of breast cancer has been reported to be associated with a greater likelihood of positive FDG uptake. Compared to invasive ductal carcinomas (IDCs), invasive lobular carcinomas (ILCs) have a lower level of FDG uptake and are detected at a significantly lower sensitivity. The role of preoperative FDG-PET for ILCs may, thus, be limited. Few data evaluating the significance of FDG-PET in ILCs are available...

Cancer stem cells (CSCs) have been suggested to serve an important role in tumor recurrence and metastasis in breast cancer. The hedgehog (Hh) signaling pathway is essential for the maintenance of breast CSCs. The present study used immunohistochemistry to investigate the expression of Patched (PTCH) and Gli1, which are the main components of the Hh signaling pathway, as well as the expression of cluster of differentiation (CD)44/CD24, which are markers for breast CSCs, in 266 patients with breast cancer. The combined expression of PTCH and Gli1 was significantly associated with larger tumors (>2...

Background and Aims:Patatin-like phospholipase domain protein 3 (PNPLA3) polymorphisms (rs738409 C>G) are associated with non-alcoholic fatty liver disease (NAFLD). We performed a systematic review and meta-analysis to examine the association of PNPLA3 polymorphisms with the spectrum and severity of this disease. Methods: Studies evaluating the association between the PNPLA3 polymorphism spectrum (fatty liver, steatohepatitis, cirrhosis, and hepatocellular carcinoma) and NAFLD were included. Pooled data are reported as odds ratios (ORs) with 95% confidence intervals...

Breast cancer metastases to the gastrointestinal tract are very rare occurrences. Among the histological subtypes of breast cancer, invasive lobular carcinomas have a high capacity of metastasis to uncommon sites including the stomach. Conversely, there has not been sufficient evidence supporting the gastric metastasis of invasive ductal carcinoma. Herein, we report a unique case of metastatic ductal breast carcinoma mimicking primary linitis plastica in a male patient, particularly focusing on the clinical and pathological features of presentation...
