There is limited data on the spectrum of molecular alterations in goblet cell carcinoids and adenocarcinoma ex goblet cell carcinoids of the appendix. We used next generation sequencing to determine mutations of potential pathogenetic and therapeutic significance in this rare group of tumors. Adequate DNA was successfully extracted in 34/46 cases and the final group included 18 goblet cell carcinoids and 16 adenocarcinoma ex goblet cell carcinoids. Illumina TruSeq™ was used for sequencing exons of a custom 282 gene panel using an Illumina HiSeq 2000...

We report three cases of thyroid sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE), which is an extremely rare variant of mucoepidermoid carcinoma (MEC). The aims of this report were to describe the clinicopathological findings, including results from immunohistochemical and fluorescence in situ hybridization analysis of thyroid SMECE, as well as to discuss the distinction between thyroid SMECE and its salivary counterpart. The cases included a 63-year-old female, a 44-year-old male, and a 66-year-old female, with all patients presenting with Hashimoto's thyroiditis...

Goblet cell carcinoid (GCC) is an uncommon tumor of the vermiform appendix. Due to a broad spectrum of morphological differentiation, subclassification and grading of GCCs remains an area of controversy. Two separate systems have proposed classifying GCC tumors into three (classical GCC; adenocarcinoma ex-GCC, signet ring cell type; adenocarcinoma ex-GCC, poorly differentiated carcinoma type) OR two subgroups (low and high grade GCC) based on morphological criteria. We independently compared the inter-observer variability associated with each classification system...

The adenoma-carcinoma sequence (ACS) and the serrated pathway are two distinct developmental routes leading to the formation of colorectal carcinoma. Recently, the doublecortin and CaM kinase-like-1 protein (DCLK1) has been reported to serve as an intestinal cancer stem cell marker and has been demonstrated to be overexpressed through the ACS; however, there is a lack of reports on the role of DCLK1 in the serrated pathway. To clarify the correlation between DCLK1 protein expression and clinicopathological characteristics of the serrated tumorigenic pathway, the present study used immunohistochemistry to examine the expression of DCLK1 in endoscopically resected samples of 62 serrated polyps [20 hyperplastic polyps (HPs), 16 traditional serrated adenomas (TSAs) and 26 sessile serrated adenoma-polyps (SSA/Ps)], as well as 20 non-serrated adenomas, 20 carcinoma in adenomas (CIAs) and 18 early pure colorectal carcinomas without any adenoma component (EPCs)...

The appendix gives rise to goblet cell carcinoids, which represent special carcinomas with distinct biological and histological features. Their genetic background and molecular relationship to colorectal adenocarcinoma is largely unknown. We therefore performed a next-generation sequencing analysis of 25 appendiceal carcinomas including 11 goblet cell carcinoids, 7 adenocarcinomas ex-goblet cell carcinoid, and 7 primary colorectal-type adenocarcinomas, using a modified Colorectal Cancer specific Panel comprising 32 genes linked to colorectal and neuroendocrine tumorigenesis...

Mixed adenoneuroendocrine carcinoma (MANEC) is a rare pathologic entity defined as a tumor exhibiting both adenocarcinoma and neuroendocrine carcinoma components. Though uncommon, these tumors show aggressive behavior and generally portend a poor prognosis. This study seeks to further define clinicopathological characteristics of MANEC to aid in accurate diagnosis and properly direct clinical management. Thirty-four confirmed MANECs were identified in our twenty-five year retrospective review of cases arising in the gastrointestinal tract...

In the present study, the effects of erlotinib on mouse tear function and corneal epithelial tissue structure were investigated. Throughout the 3 weeks of treatment, no notable differences were observed in the body, eye or lacrimal gland weights of the control and experimental mice. However, in the experimental group, the tear volume and break‑up times of tear film were significantly lower following treatment with erlotinib compared with the control group. Corneal fluorescein staining in the experimental group revealed patchy staining, and the Lissamine green staining and inflammatory index were significantly higher in the experimental group at 3 weeks than in the control group...

Sodium 4-phenylbutyrate (PBA) exerts therapeutic effects in a wide range of pathologies. A previous study by the present authors revealed that intraperitoneal administration of PBA suppresses the onset of dextran sulfate sodium (DSS)-induced colitis in mice. In the present study, the effects of orally administered PBA are investigated, as this route of administration is more clinically relevant. The therapeutic efficacy of PBA (10 mg/12 h) in mice with experimental colitis was assessed based on the disease activity index, production of inflammatory cytokines, colon length and histopathological investigations...

It is increasingly perceived that dietary components have been linked with the prevention of intestinal cancer. Cranberry is a rich source of phenolic constituents and non-digestible fermentable dietary fiber, which shows anti-proliferation effect in colorectal cancer cells. Herein, we investigated the efficacy of long-term cranberry diet on intestinal adenoma formation in Apcmin/+ mice. Apcmin/+ mice were fed a basal diet or a diet containing 20% (w/w) freeze-dried whole cranberry powder for 12 weeks, and the number and size of tumors were recorded after sacrifice...

Asthma is a chronic pulmonary disease that affects an estimated 235 million people worldwide, but asthma drugs have many adverse effects. Opuntia humifusa (eastern prickly pear) has been used as a food and traditional medicine worldwide; however, its anti-asthmatic effects have not been reported. We evaluated O. humifusa as a potential therapeutic or preventive component of anti-asthmatic drugs. We divided ovalbumin-sensitized mice into the following groups: normal control, asthma-induced control, dexamethasone-treated group (positive control), 50 mg/kg O...

Methyl gallate is a gallotannin widely distributed in nature. Previous studies have demonstrated its antioxidant, anti-inflammatory, antimicrobial and anti-tumor activities. In the present study, the activity of methyl gallate on experimental models of inflammatory bowel disease has been investigated. Experimental colitis was induced in Sprague-Dawley rats through the intracolonic instillation of an acetic acid solution (2 mL, 4% v/v). Methyl gallate (100 and 300 mg/kg, p.o.) and the reference drug mesalazine (100 mg/kg, p...

The aim of this study is to show if cyclosporine has an antiallergic role in a rat model of ovalbumin-induced allergic rhinitis. The 54 rats were divided into six equal groups. The first group was a negative control group without induced allergic rhinitis; the second group a positive control with induced allergic rhinitis not receiving treatment. The remaining four groups, after induction of allergic rhinitis, received intranasal cyclosporine treatment in doses of 0.05, 0.1, or 0.2% or nasal steroid treatment...

Krukenberg tumor, defined as metastatic adenocarcinoma to the ovary containing at least 10% signet ring cells, usually arises from the stomach but can also originate from other sites. We reviewed 17 metastatic breast carcinomas to the ovary with signet ring cells to potentially identify features indicative of mammary origin as opposed to other possible primary sites. The patients ranged from 41 to 76 (mean, 53.6) yr. Fourteen had a prior history of invasive breast carcinoma (invasive ductal carcinoma, 4; invasive lobular carcinoma, 3; adenocarcinoma not otherwise specified, 3; carcinoma with ductal and lobular features, 2; and unspecified carcinoma, 2) and metastases were identified 2 to 284 (mean, 79) mo after the original diagnosis...

REVIEW
Lon Wolf R Fong, David C Yang, Ching-Hsien Chen
Emerging evidence implicates myristoylated alanine-rich C-kinase substrate (MARCKS), a major substrate of protein kinase C (PKC), in a critical role for cancer development and progression. MARCKS is tethered to the plasma membrane but can shuttle between the cytosol and plasma membrane via the myristoyl-electrostatic switch. Phosphorylation of MARCKS by PKC leads to its translocation from the plasma membrane to the cytosol where it functions in actin cytoskeletal remodeling, Ca(2+) signaling through binding to calmodulin, and regulation of exocytic vesicle release in secretory cells such as neurons and airway goblet cells...

Barrett esophagus (BE) predisposes patients to the development of esophageal adenocarcinoma (EAC). However, the global definition of BE is controversial. Pathologists in Europe and the United States require intestinal metaplasia (IM) within columnar-lined mucosa (CLM) in the tubular esophagus to diagnose BE, whereas in the UK and Japan only the presence of CLM is required. To aid in establishing an appropriate definition for BE, we evaluated whether IM accompanies EAC in a US patient cohort. We examined a series of 139 consecutive patients who underwent endoscopic mucosal resections or esophagectomies for EAC performed at a US tertiary care center...

Intestinal mucus secretion is critical in maintaining mucosal host defense against a myriad of pathogens by preventing direct association with the epithelium. Entamoeba histolytica specifically binds colonic MUC2 mucin and also induces potent hypersecretion from goblet cells; however, characterization of the nature of the mechanisms controlling mucus release remains elusive. In this report, we identify vesicle SNARE vesicle-associated membrane protein 8 (VAMP8) present on mucin granules as orchestrating regulated exocytosis in human goblet cells in response to the presence of E...

Thymic carcinoma is a rare, aggressive disease with a low 5-year survival rate. The most common histological neoplastic thymic tumor subtype is squamous cell. We describe an interesting case of a 39-year-old woman who presented with mucinous adenocarcinoma that originated in the thymus and was treated via radical resection and venoplasty of the superior vena cava (SVC). Macroscopically, the resected tumor contained a solid region and multiple cysts with abundant mucin. Microscopic examination showed a papillary growth pattern of goblet cells with round nuclei...

SATB2 is a sensitive marker for colorectal adenocarcinomas. No study has investigated its diagnostic utility in metastatic Krukenberg tumors (MKTs) of the ovary. Here we performed immunohistochemical staining SATB2 in 70 MKTs of various origins (stomach 27, colorectum 13, appendix 20 including 19 metastatic adenocarcinomas ex goblet cell carcinoids [AdexGCC] and 1 conventional poorly differentiated carcinoma with signet ring cells, breast 5, bladder 3, lung 2) to assess its diagnostic utility. We also compared SATB2 with CDX2, CK7, CK20, chromogranin, and synaptophysin in MKTs of gastric origin (MKTs-stomach), those of colorectal origin (MKTs-colorectum) and those due to appendiceal AdexGCCs (MKT-AdexGCCs) for their sensitivity and specificity to distinguish these tumors...
