ABSTRACT
GastricNeuroendocrinetumors(TNEG), aremalignant
neoplasm of epithelial strain linked to the APUD
system (
Amine Precursor Uptake Descarboxilase) that
originate from gastric enterocromaffin-like cells. They
represent 7 - 8% of the neuroendocrine neoplasms of
the gastrointestinal tract. They have characteristics
of the diffuse endocrine system and neural elements;
hence the origin of his name. Historically they have
also been called carcinoid tumors, however this term
is recognized as archaic and ambiguous, which is
why it has fallen into disuse. There has been a notable
increase in the diagnosis of TNEG in recent decades
and the cause of this phenomenon is not clear yet. In
the United States, for example, in the last 35 years the
incidence of TNEGs has increased 10 times. Hence the
importance of knowing about these tumors, because
although they are not the most frequent gastric
neoplasms, their diagnosis has increased considerably.
