Abstract
Esophageal hyperplastic polyps (HPs) are a rare benign polypoidal growth most commonly resulting from gastroesophageal reflux disease (GERD). The lesion is asymptomatic in most patients unless large enough to cause luminal obstruction or gastrointestinal bleeding. The treatment of choice is endoscopic resection if it becomes symptomatic. Here, we report a case of a 51-year-old woman presenting with dyspeptic symptoms and upper gastrointestinal bleeding. An upper gastrointestinal endoscopy showed a large polyp with active oozing of blood at the gastroesophageal junction (GEJ), which was removed endoscopically after injecting adrenaline at its base. Histopathological analysis was suggestive of HPs.

Abstract
The association of eosinophilic esophagitis and esophageal polyps has been
reported in the literature but remains a rare finding in both adults and
children. The patient in this case report presented with progressively worsening
dysphagia secondary to eosinophilic esophagitis and an esophageal polyp.
Dysphagia is always abnormal, and endoscopic evaluation is essential. Dysphagia
is a well-known symptom in patients with eosinophilic esophagitis. While
esophageal polyps as a whole are less common in the pediatric population, they
should not be overlooked as a possible cause of dysphagia and esophageal
obstruction.

Abstract
Hyperplastic polyp of the esophagus is a rare condition and most of the time asymptomatic. We report a case of a 69-year-old female with scleroderma who presented with worsening dysphagia, regurgitation of food, and non-cardiac chest pain. Upper endoscopy showed a nodular lesion in the distal esophagus. Biopsy of the lesion showed features of hyperplastic polyp without any metaplastic changes. She was started on anti-acid therapy and an outpatient upper endoscopy was performed which showed no residual polyp.

Abstract
This review provides an overview of different types of gastric epithelial polyps. The polyps are classified based on their cell or epithelial compartment of origin. Some of these polyps can be considered reactive or nonneoplastic, whereas others are neoplastic in origin, are sometimes associated with a hereditary polyposis/cancer syndrome, and may have malignant potential. The aim of this review is to provide a pragmatic overview for the practicing pathologist about how to correctly diagnose and deal with gastric epithelial polyps and when (not) to ponder, and when (not) to panic.

Abstract
In 2 high-risk prostate cancer patients, PET scans revealed focally increased Ga-prostate-specific membrane antigen uptake in the distal esophagus. Both patients had hiatus herniation on gastroscopy, and esophageal biopsies revealed acute and chronic inflammation in both patients and a benign hyperplastic polyp in one of the patients. Recently, reports have demonstrated that inflammation can cause false-positive findings on Ga-prostate-specific membrane antigen PET/CT, and these cases present this phenomenon in the esophagus as well.

Abstract
Most solitary gastrointestinal (GI) polyps in children are either inflammatory or hamartomatous. Solitary hyperplastic polyp, sentinel polyp and solitary adenomatous polyp have been occasionally diagnosed in adults, but very rarely reported in Korean children. We recently came across a case with adenomatous polyp in the colon, a case with hyperplastic polyp beneath the gastroesophageal junction, a case with hyperplastic polyp in the prepyloric area, and a case with sentinel polyp in the distal esophagus, which are unusual pathologic types in children. These mucosal lesions were diagnosed incidentally during elective endoscopic examinations for GI symptoms. Most polyps do not cause significant symptoms, so the diagnosis might be delayed, especially in children, in whom GI endoscopy is not commonly performed for screening purpose as in the adults.

Abstract
A 23-year-old Caucasian male with Neurofibromatosis Type I (NF-I) was found to have a submucosal nodule at the gastroesophageal junction (GEJ) and underwent endoscopic submucosal dissection. Histological examination revealed two different lesions within the nodule. The dominant lesion was inflammatory/hyperplastic (juvenile-like) polyp with obliterative vasculopathy while the smaller lesion was a neurofibroma. Gastric/GEJ lesions in NF-I are very rare with only seven cases reported in the literature. Three cases of juvenile-like gastric polyps (located in the antrum, greater curvature, and fundus) have been reported in adult NF-I patients. An inflammatory polyp associated with a neurofibroma has only been described once in the pediatric literature but never in an adult. Our case is unique from those previously described in the literature due to the age of the patient, the presence of 2 histologically separate lesions in one endoscopically evident lesion, and the presence of obliterative vasculopathy in the juvenile-like polyp.

Abstract
Benign esophageal lesions have a wide spectrum of clinical and pathologic features. Understanding the endoscopic and pathologic features of esophageal lesions is essential for their detection, differential diagnosis, and management. The purpose of this review is to provide updated features that may help physicians to appropriately manage these esophageal lesions. The endoscopic features of 2997 patients are reviewed. In epithelial lesions, the frequency of occurrence was in the following order: glycogenic acanthosis, heterotopic gastric mucosa, squamous papilloma, hyperplastic polyp, ectopic sebaceous gland and xanthoma. In subepithelial lesions, the order was as follows: hemangioma, leiomyoma, dysphagia aortica and granular cell tumor. Most benign esophageal lesions can be diagnosed according to their endoscopic appearance and findings on routine biopsy, and submucosal lesions, by endoscopic resection. Management is generally based upon the confidence of diagnosis and whether the lesion causes symptoms. We suggest endoscopic resection of all granular cell tumors and squamous papillomas because, while rare, these lesions have malignant potential. Dysphagia aortica should be considered in the differential diagnosis of dysphagia in the elderly.

Abstract
Benign tumors of the esophagogastric junction are rare and mostly found incidentally during endoscopic or radiological procedures which are often performed for unrelated reasons. Epithelial lesions must be distinguished from subepithelial findings, where the latter are far more common and mostly represent benign leiomyomas, especially in the esophagus. Some benign tumors, such as small gastrointestinal stromal tumors, have malignant potential and must therefore be distinguished from completely benign lesions. Epithelial tumors can be diagnosed by standard endoscopic biopsies, whereas tissue acquisition of subepithelial lesions is more challenging. For this purpose endosonography is a valuable tool even before tissue acquisition or resection is performed. Endosonography can identify the gastrointestinal wall layer from which the lesion arises and gives additional information by identification of characteristic echographic features. Endoscopic resection techniques are used to remove those tumors that originate from the mucosa or submucosa. Some authors have even described resection of tumors originating from the deep muscle layer, but these techniques have a significant risk of perforation. Several surgical techniques are available for complete resection ranging from laparoscopic enucleation to combined endoscopic laparoscopic (rendezvous) techniques and abdominothoracic approaches. The current diagnostic and therapeutic challenges regarding benign tumors of the esophagogastric junction are outlined in this review article.

Abstract
Esophageal polyps are uncommon findings in pediatric patients, and reports have been limited to case reports. Esophageal polyps have been previously ascribed to esophagitis secondary to gastroesophageal reflux, medications, infections and recurrent vomiting. They have been associated with underlying conditions such as hiatal hernia, Barrett's esophagus, eosinophilic esophagitis and Crohn's disease. Presenting complaints of children with esophageal polyps have included vomiting, dysphagia, hematemesis and abdominal pain. The aim of this paper is to characterize the incidence, clinical presentation and progression, histologic subtypes and associated mucosal abnormalities in children with esophageal polyps. A retrospective multicenter study was performed at four institutions identifying diagnosis of esophageal polyps in pediatric patients (<21 years). Information was obtained from patient charts, endoscopy reports and histopathology reports. Specimens and slides were examined by experienced pediatric pathologists for all included cases. Esophageal polyps were identified in 13 patients (9 M) from 9438 esophagogastroduodenoscopies (0.14%). Mean age of subjects was 9.2 years. Vomiting was the most common indication for endoscopy. Polyp location was at the gastroesophageal junction in 7 of the 13 cases. Most polyps were inflammatory (n = 7). Esophagitis was noted in 69% of those with esophageal polyps. Repeat endoscopies in six patients at a mean interval of 8 months noted persistence of polyps in all six patients. This paper is the first to characterize esophageal polyps in pediatrics. These polyps are rare in children and often are associated with esophagitis. Presenting complaints seem to vary by age. Polyps did not consistently change with either time or acid suppression. The optimal management strategy has yet to be defined and likely depends on the underlying pathophysiologic process.

Abstract
HIV infections frequently affect the oral cavity, and local changes may be utilized as indicators of immunosuppression in HIV-positive patients. Morphometric and morphological features of the lining, masticatory, and specialized epithelium of the oral mucosa were studied in 12 HIV-positive and 12 HIV-negative patients autopsied from 2007 to 2010. Mucosal samples from the cheek, gingival, and tongue of 24 individuals were fixed in Carnoy solution and stained with hematoxylin-eosin. Various morphometric characteristics (epithelial thickness, number of cell layers, mean cell diameter) and morphological parameters (basal layer hyperplasia, exocytosis of inflammatory cells, glycogenic acanthosis, cell ballooning degeneration) were then measured. The HIV-positive group had a greater epithelial thickness (mean: 304.4μm) and a higher mean cell diameter (11.84μm), whereas the HIV-negative group had more epithelial layers (26.7). Basal layer hyperplasia did not differ significantly between the two groups, but exocytosis of inflammatory cells, glycogenic acanthosis, cell ballooning, and spongiosis were more prevalent in the HIV-positive group. Our findings demonstrate that HIV infection causes diverse epithelial changes in the oral cavity, including thickening, increased cell diameter, increased migration of inflammatory cells, and inter- and intra-cellular edema.

Abstract
Hyperplastic (inflammatory) polyps (HPs) of the gastric corpus and antrum typically develop in association with chronic gastritis. However, little is known regarding the etiology, pathologic features, and natural history of HPs of the gastroesophageal junction (GEJ). We have noted, anecdotally, that GEJ HPs often occur in patients without gastric pathology. The aim of this study was to evaluate the clinical, pathologic, and outcome features of patients with HPs of the GEJ, and to compare the data with a control group of individuals with HPs in the gastric corpus or antrum. One hundred thirty-four consecutive polyps of the GEJ were identified by a 5-year search through the pathology files of a major tertiary-care hospital. Of these, 46 (36%) polyps from 46 patients met the pathologic criteria for HPs and formed the basis of this study. The 46 study patients, and their polyps, were evaluated for a wide variety of clinical, endoscopic, and pathologic features including outcome on follow-up endoscopy. The findings were compared with 46 HPs from 46 patients of the distal stomach (antrum or corpus) that were obtained randomly from the same 5-year period. Compared with patients with gastric antral or corpus HPs, patients with HPs of the GEJ were significantly younger in age (mean age, 55.9 y vs. 63.0 y; P=0.04). Pathologically, GEJ HPs showed a significantly higher rate of multilayered epithelium (P=0.06) and association with Barrett esophagus (BE) (P=0.0001) compared with distal gastric HPs. All BE-associated GEJ HPs were associated with either ultrashort (<1 cm) or short segment (1 to 3 cm) BE. All other pathologic variables, including intestinal metaplasia, were similar to those of distal gastric HPs. In a subanalysis, BE-associated GEJ HPs (33% of all GEJ HPs) showed a higher male to female ratio and a higher rate of intestinal metaplasia compared with all other HPs. Furthermore, none of the BE-associated GEJ HPs were associated with chronic active gastritis versus the non-BE-associated GEJ HPs, although this was not statistically significant. Only 1 HP (from the GEJ) from both the study and control groups was associated with a neoplasm (signet-ring cell carcinoma). On follow-up, 1 patient with a GEJ HP and 4 with distal gastric HPs developed recurrent HPs and none of the patients from either patient group developed dysplasia or carcinoma. In conclusion, unlike HPs of the gastric corpus or antrum, a significant proportion of HPs of the GEJ arise in association with BE and without gastric pathology. In patients with BE, the columnar-lined segment is often ultrashort, and thus, an HP may be the first clinical/endoscopic manifestation of that disorder.

Abstract
Hyperplastic esophagogastric polyps usually occur in the distal esophagus or gastroesophageal junction and have been associated with damage to the esophageal mucosa. Histologically these polyps show hyperplastic gastric foveolar and/or squamous epithelium with inflamed stroma. Reports of esophagogastric polyps in the pediatric population are rare. Most of these reports only describe chronic inflammation within the lamina propria of the polyp, with only rare reports specifying the presence of epithelial hyperplasia. There have been 2 previous cases of hyperplastic esophagogastric polyps occurring in the context of neurofibromatosis type 1 (NF-1) in a single article. Here we report a 3rd case of hyperplastic esophagogastric polyps occurring in an 11-year-old male with NF-1. This case is unique in that there were 2 polyps in the same patient and in that the polyps showed hyperplastic gastric peptic glands in addition to foveolar-type and focal squamous epithelium. The case is discussed and literature reviewed.

Abstract
Gastric polyps can be broadly defined as luminal lesions projecting above the plane of the mucosal surface. They are relatively frequent in routine pathology practice, where the main goal is to rule out the possibility of malignancy. Various subtypes of gastric polyps are recognized and generally divided into nonneoplastic and neoplastic. We will review herein only a limited subset of gastric polyps representing the most common or, sometimes, challenging.

Abstract
Hyperplastic polyps are by far the most common benign tumors in the stomach larger than 5mm. Although the malignant potential of hyperplastic gastric polyps was originally denied, a low risk for carcinomatous conversion is now recognized. Its has been recommended that all gastric polyps of 5mm or more in diameter have to be removed. We present here the case of a large hyperplastic gastric polyp located at the esophagogastric junction with endoscopic malignant appearance. The description of its endoscopic and histological characteristics gives us the opportunity to discuss the difficulty of endoscopic diagnosis in the case of gastric polyps and to remind their prognosis.

Abstract
AIM To assess the prevalence of oesophagitis, Barrett's oesophagus (BE) and other oesophageal mucosal abnormalities in patients with systemic sclerosis (SSc) without prior selection on digestive clinical presentation. We also investigated the association between oesophageal endoscopic and manometric data with clinical manifestations of SSc. METHODS Oesophageal endoscopy and manometry were performed in 133 consecutive patients with SSc, receiving proton pump inhibitor (PPI) therapy since SSc diagnosis. RESULTS Endoscopy revealed oesophagitis in 43 patients (32.3%), BE in 9 patients (6.8%), candidiasis in 7 patients (5.3%) and hyperplastic polyp arising in ectopic gastric mucosa in 1 patient. Patients with severe oesophageal motor impairment further exhibited a higher prevalence of interstitial lung disease (ILD) when compared with those without. CONCLUSION Our study underlines the high frequency of oesophageal mucosal abnormalities in unselected SSc patients receiving long-term PPI therapy. A relationship between oesophagitis/BE and severe manometric motor disturbances was established; these patients may require a higher regimen of PPI. Finally, our series indicates a correlation between severe oesophageal motor disturbances and evidence for ILD in patients, suggesting that gastro-oesophageal reflux may be one of the contributing factors of ILD in SSc; this subgroup of patients may require close monitoring of lung parameters.

Abstract
AIM: To report the endoscopic treatment of large hyperplastic polyps of the esophagus and esophago-gastric junction (EGJ) associated with Barrett’s esophagus (BE) with low-grade dysplasia (LGD), by endoscopic mucosal resection (EMR).
METHODS: Cap fitted EMR (EMR-C) was performed in 3 patients with hyperplastic-inflammatory polyps (HIPs) and BE.
RESULTS: The polyps were successfully removed in the 3 patients. In two patients, with short segment BE (SSBE) (≤ 3 cm), the metaplastic tissue was completely excised. A 2 cm circumferential EMR was performed in one patient with a polyp involving the whole EGJ. A simultaneous EMR-C of a BE-associated polypoid dysplastic lesion measuring 1 cm x 10 cm, was also carried out. In the two patients, histologic assessment detected LGD in BE. No complications occurred. Complete neosquamous re-epithelialization occurred in the two patients with SSBE. An esophageal recurrence occurred in the remaining one and was successfully retreated by EMR.
CONCLUSION: EMR-C appears to be a safe and effective method for treating benign esophageal mucosal lesions, allowing also the complete removal of SSBE.

Abstract
The nicotinic acetylcholine receptor is a ligand-gated channel that mediates signalling at the vertebrate neuromuscular junction. It is a pentameric complex of four different subunits, assembled with a stoichiometry of alpha 2 beta gamma delta. Muscle-like alpha-subunits have been cloned from Torpedo, mouse, calf, rat, chicken, human and Xenopus, and only a single alpha-subunit complementary DNA from each species has been detected. We report here the cloning and characterization of a second muscle alpha-subunit cDNA from Xenopus, and show that this and a previously reported Xenopus alpha-subunit cDNA are encoded by distinct genes. The novel alpha-subunit reported here is expressed uniquely in oocytes; but both types of alpha-subunit are coexpressed throughout muscle development. This latter observation indicates that the expression of these two alpha-subunits is different from a previously reported developmental 'subunit-switch' mechanism used to generate channel diversity.
