Discuss the endoscopic diagnosis of carcinoid tumour?

  • Carcinoid tumours arise from the neuroendocrine cells in the mucosa and submucosa.

  • They may be intramural masses, or they may protrude into the lumen as polypoid nodules. The overlying gastric or intestinal mucosa may be intact or have focal ulceration.
  • Although carcinoid tumours can be subepithelial, deep biopsies often helps in establishing the diagnosis histologically.
