abstractintroduction: hyperplastic polyps of the esophago-gastric junction are seen during endoscopic evaluation of upper gastrointestinal tract. they are usually asymptomatic and discovered accidentally during endoscopic evaluation for other problems. these protrusions are mucosal regenerative response to surrounding mucosal injury. case: here we present a 9-year-old boy presenting with abdomi...

pedunculated polyp A 46-year-old woman was admitted to a local medical center with abdominal pain and discomfort, which she had experienced for 6 months. Her medical history was unremarkable. Esophagogastroduodenoscopy (EGD) showed a huge pedunculated polyp located in the stomach body. The patient was referred to our hospital for endoscopic submucosal dissection (ESD) with the working diagnosis...

Pseudomelanosis is a rare endoscopic finding of the upper gastrointestinal tract characterized by hemosiderin deposits in histiocytes of lamina propria. We report a case of 72-year-old lady on chronic oral iron supplementation diagnosed with gastric hyperplastic polyps with background pseudomelanosis of stomach and duodenum. Concomitant occurrence of gastric pseudomelanosis, duodenal pseudomela...

We report the clinicopathological findings of two patients with ectopic gastric mucosa within the gall ladder. The first patient, a 78 year old man, was asymptomatic. He was admitted to hospital for a colon adenocarcinoma. Intraoperatively, a firm nodule was palpable in the gall bladder. Histological examination of the resected specimen revealed a body type gastric mucosa in the submucosa, adja...

Inflammatory fibroid polyp (Vanek tumor) is a rare benign lesion which originates from the submucosa of the gastrointestinal tract. The most common locatization is the gastric antrum. Although the etiopathogenesis is unknown, it is thought that inflammatory fibroid polyps are the result of reactive inflammatory processes because of their eosinophilrich stroma. Microscopically, fibrous connectiv...

Molecular genetic analyses of archival formalin-fixed, paraffin-embedded (FFPE) pathological specimens taken at biopsy or autopsy, are occasionally compromised because the DNA molecules therein are inevitably degraded. Furthermore, since these tissue samples comprise various cell types, the analyses based on mixtures of such heterogeneous populations often fail to reflect the nature of the affe...
