Ge. Feurle, ARGYROPHIL CELL HYPERPLASIA AND A CARCINOID-TUMOR IN THE STOMACH OF APATIENT WITH SPORADIC ZOLLINGER-ELLISON SYNDROME, Gut, 35(2), 1994, pp. 275-277
In the rat, hypergastrinaemia induced by drug treatment with omeprazol
e or potent H-2-receptor antagonists leads to the development of gastr
ic enterochromaffin-like cell carcinoids. In man, gastric carcinoids i
nduced by hypergastrinaemia have been described only in patients with
chronic atrophic gastritis type A and in patients with the multiple en
docrine neoplasia syndrome type 1. This patient with Zollinger-Ellison
syndrome without gastric mucosal atrophy and without evidence of the
multiple endocrine neoplasia syndrome developed an argyrophil gastric
carcinoid tumour. This observation indicates that hypergastrinaemia in
the sporadic Zollinger-Ellison-syndrome may induce gastric-carcinoids
.
