Abstract
CONTEXT.— The cause of pancreatic acinar metaplasia (PAM) at the distal esophagus/esophagogastric junction is still controversial. Whereas some authors believe it is congenital, others believe it is acquired because of inflammation of the gastric cardia, and more recently it was proposed to be due to chronic proton pump inhibitor use based on a study in rats. OBJECTIVE.— To determine whether there is correlation between chronic proton pump inhibitor use and PAM in humans. We also investigated the correlation between several clinical and pathologic factors and PAM. DESIGN.— Four hundred forty-four consecutive biopsies from the distal esophagus/esophagogastric junction were reviewed for the presence of PAM, which was then correlated with several clinical and pathologic findings. RESULTS.— Pancreatic acinar metaplasia was found in 71 patients (16%). Pancreatic acinar metaplasia was significantly associated with patient age younger than 51 years ( P < .001), chronic carditis ( P = .01), and chronic proton pump inhibitor use ( P = .008). Surprisingly, we also found significant association between PAM and chronic nonsteroidal anti-inflammatory drug use ( P < .001). These associations, including that with chronic nonsteroidal anti-inflammatory drug use, remained significant in multivariate analysis. CONCLUSIONS.— Our findings confirm the previous reports of significant association between PAM and chronic carditis and the findings from animal studies of association with chronic proton pump inhibitor use. The strong association with chronic nonsteroidal anti-inflammatory drug use has not been previously reported and warrants further studies.

Abstract
Ectopic pancreas is a rare congenital disorder defined as pancreatic tissue lacking vascular or anatomic communication with the normal body of the pancreas. Most cases of ectopic pancreas are asymptomatic, but it may become clinically evident depending on the size, location and the pathological changes similar to those observed in case of the normal pancreas. It is often an incidental finding and can be located at different sites in the gastrointestinal tract. The most common locations are: the stomach, duodenum or the proximal part of small intestine. The risk of malignancy, bleeding and occlusion are the most serious complications. Despite the development in diagnostics, it still remains a challenge for the clinician to differentiate it from neoplasm. In this report, we described a case of 28-years old woman who presented recurrent epigastric pain. The upper gastrointestinal endoscopy revealed gastrointestinal stromal tumor on the border of the body and antrum of the back wall of great curvature of the stomach. The histopathological examination after surgery showed heterotopic pancreatic tissue. Ectopic pancreas should be considered in the differential diagnosis of gastric mass lesions.

Abstract
The author describes a case of pancreatic heterotopia in the gastric antrum detected after histopathological and ultrastructural studies. Bioptic fragments were processed in part for optic microscopy and in part for electron transmission microscopy. Regressive changes were found in the cytoplasm of the exocrine secreting epithelia that led to necrosis of the cells. The changes are consequential and more markedly involve the base area of the secretory epithelia. The changes observed are to be attributed to the absence of excretory activity by the epithelia due to regressive damage of the organelles carrying out this activity.

Abstract
Pancreatic heterotopia is a well-recognized entity occurring at a variety of sites in the gastrointestinal tract. However, only a handful of patients have been described with this abnormality at the gastroesophageal junction. Cytologic descriptions of pancreatic heterotopia in general are scant in the literature. We report the cytologic findings of ectopic pancreatic tissue at the gastroesophageal junction in a 41-year-old female, which was initially identified by endoscopic ultrasound and fine-needle aspiration. Cytologic examination of Papanicolaou-stained smears revealed clusters of benign-appearing ducts and small acini mixed with inflammatory cells. Hematoxylin and eosin staining of the Tru-Cut biopsy revealed benign pancreatic tissue. The patient underwent surgical resection due to symptoms related to inflammation of the heterotopic pancreatic tissue. The increasing use of endoscopic ultrasound and fine-needle aspiration for the diagnosis of gastrointestinal tumors makes the recognition of pseudoneoplastic lesions at unusual sites an important step in optimum patient management.

Abstract
CONTEXT Inlet patch is a congenital anomaly of the cervical esophagus consisting of gastric mucosa. Case reports have documented the histologic type and its associated complications. OBJECTIVE To report the prevalence and histologic types of inlet patch as well as its association with Barrett esophagus and Helicobacter pylori-associated gastritis. DESIGN We reviewed 1821 consecutive pathology reports from endoscopies of the upper gastrointestinal tract between 1995 and 2002 and identified 20 patients with inlet patch. The patients' ages ranged from 16 to 75 years (mean, 55 years). We examined biopsies from these patients of the cervical esophagus, distal esophagus, and antrum that had been stained with hematoxylin-eosin and the Steiner stain. Biopsies from the cervical esophagus composed of nonoxyntic gastric mucosa were also stained for gastrin-producing cells. RESULTS In our patient population, inlet patch occurred in 1.1% of all patients in whom an inlet patch had been searched for endoscopically and a biopsy performed. In the inlet patch, oxyntic mucosa was the most common histologic type (11/20), followed by cardiac mucosa (5/20). Four specimens of the inlet patch contained only foveolar epithelium and were therefore considered too superficial to be classified. Twelve of 20 biopsies of the inlet patch were inflamed, and 1 of them was associated with H pylori. Pancreatic acinar tissue was noted in 2 patients; no intestinal metaplasia was found. In the distal esophagus, 4 patients with inlet patch had distal esophagitis, 4 had Barrett esophagus, 5 had oxyntic mucosa, 3 had pancreatic acinar tissue (1 coexisting with oxyntic mucosa), and 5 presented with only unremarkable esophageal squamous mucosa. Antral gastritis was seen in 2 patients, 1 of them with H pylori. The same patient also had H pylori in the inlet patch. CONCLUSION Inlet patch occurred in about 1% of our study population. Oxyntic mucosa constituted the most common histologic type; inflammation was common. The H pylori infection of the inlet patch correlated with that of the antrum. None of the inlet patch biopsies showed intestinal metaplasia. Pancreatic acinar tissue occurred with similar frequency in the inlet patch and distal esophagus. Esophagitis was noted in 25% of the patients with inlet patch, and Barrett esophagus was noted in 20%.
