  • Chapter
Book cover Die Onkologie

  • 339 Accesses

Zusammenfassung

Für die Nomenklatur der endokrinen Tumoren des Gastrointestinaltrakts werden die in der Übersicht zusammengefassten Begriffe synonym verwendet. Der Terminus „Karzinoid“ ist streng genommen den endokrinen Tumoren des Magen-Darm-Trakts (Vorder-, Mittel- und Hinterdarm) und den sich aus dem Vorderdarm abgeleiteten Organsystemen wie dem Bronchialsystem vorbehalten (⊡ Tabelle 67.1; Arnold 1997). Endokrine Pankreastumoren fallen danach nicht unter den Karzinoidbegriff, da diese sich aus den Langerhans-Inseln und nicht aus dem diffusen endokrinen Zellsystem des Gastrointestinaltrakts entwickeln. Zumindest bei Vertebraten entstehen die Langerhans-Inseln aus einem eigenständigen Inselorgan, das während der Ontogenese mit dem exokrinen Pankreasanteil verschmilzt.
