Zusammenfassung
Die neuroendokrinen Tumoren des Pankreas sind insgesamt selten, gehören jedoch zu den häufigsten endokrinen Neoplasien des Abdominalraums. In den meisten Fällen handelt es sich um solitäre Tumoren, aufgebaut aus monomorphen Zellen. Funktionell aktive Tumoren sind mit charakteristischen Syndromen verbunden. Anhand von morphologischen, immunhistochemischen und biologischen Kriterien wird zwischen gut differenzierten Tumoren mit benignem Verhalten oder solchen mit fraglicher Dignität, gut differenzierten (niedrigmalignen) Karzinomen und niedrig differenzierten (hochmalignen) Karzinomen unterschieden. In den letzten Jahren hat der Anteil der nicht-funktionellen Tumoren zugenommen.
Abstract
The neuroendocrine tumors of the pancreas are rare, but belong to the most common endocrine neoplasms of the abdomen. In most cases they present as solitary tumors, composed of monomorphic cells. Functionally active cells are associated with characteristic hormonal syndromes. Using morphological, immunohistochemical and biological criteria, the classification distinguishes between well differentiated tumors with benign or uncertain behavior, well differentiated (low grade malignant) carcinomas and poorly differentiated (high grade malignant) carcinomas. In recent years the percentage of non-functional tumors has increased.
