• gastric plexiform angiomyxoid myofibroblastic tumor
  15 June 2009

  Plexiform angiomyxoid myofibroblastic tumour is a recently described new entity of a presumably benign mesenchymal gastric tumour.
  The tumour is characterised by bland spindle cells in a plexiform pattern, a mucinous extracellular matrix and a network of thin blood vessels.
  There is a strong positivity for alpha-smooth muscle actin and a low proliferation index (<2%).
  The tumour had no C-KIT or CD34 expression and no mutation in the C-KIT and PDFGRalpha genes.

• Zollinger–Ellison syndrome-associated gastric carcinoid tumor
  5 May 2009

  Between 5 and 10 percent of gastric carcinoids are associated with the Zollinger–Ellison syndrome.
  Like carcinoids associated with CAG-A, carcinoids associated with the Zollinger–Ellison syndrome are thought to arise from enterochromaffin-like cells in patients with hypergastremia and are associated with hyperplasia of surrounding enterochromaffin-like cells.
  Carcinoids associated with the Zollinger–Ellison syndrome occur almost exclusively in patients with multiple endocrine neoplasia type (...)

  Gastric Carcinoid Tumors
  Definition: Neuroendocrine neoplasms arising from enterochromaffin-like (ECL) cells measuring more than 0.5 mm of diameter in size or invading submucosa
  Originating from the histamine-containing enterochromaffin-like (ECL) cells of the embryologic foregut, gastric carcinoid tumors represent approximately 1.8% of all gastric neoplasms and approximately 7% of all carcinoids.
  Because they are most often discovered incidentally during endoscopy, the incidence of (...)
