BACKGROUND Occurrence of metastatic cancer to the stomach is rare, particularly in patients with prostate cancer. Gastric metastasis generally presents as a solitary and submucosal lesion with a central depression. CASE PRESENTATION We describe a case of gastric metastasis arising from prostate cancer, which is almost indistinguishable from the undifferentiated-type gastric cancer. A definiti...

The risk of misdiagnosing neoplastic cells typically infiltrating an epithelium forming a lymphoepithelial lesion as poorly differentiated gastric cancer in endoscopic biopsies, particularly in low-grade mucosa-associated lymphoid tissue (MALT) lymphomas, is described. A 76-year-old woman was referred for management of a poorly differentiated gastric adenocarcinoma. Diagnostic endoscopy in our ...

  The gastric inflammatory fibroid polyp (IFP) is a rare benign tumor of unknown etiology that is localized mainly in the antrum and presents endoscopically as submucosal mass. The lesion manifests as abdominal pain, weight loss, bleeding, dyspeptic symptoms, and iron deficiency anemia. We report a case of gastric IFP presented with microcytic anaemia, dyspepsia, malena and weight loss. Endosc...

Objectives Mucin phenotype is a tool to classify gastric cancer, but the relationship between mucin and its malignancy still controversial. This study aimed clarify malignant potential of cancer. Methods A total 82 cases early-stage differentiated adenocarcinoma (submucosal invasion cases) obtained from surgeries were studied by immunohistochemistry. Gastric E-cadherin expression analyzed in mu...

Gastric foregut cyst is a rare congenital disease. In this report, a gastric foregut cyst in a 22-year-old male patient is presented. Fluid-filled gastric ultrasonography and computed tomography demonstrated a cystic, calcified lesion attached to the anterior gastric wall. The same lesion was observed using upper gastrointestinal endoscopy. An exploratory laparotomy revealed a non-communicating...
