Duodenal endocrine cell tumors are divided into five main groups: gastrin-containing G-cell tumors, somatostatin-containing D-cell tumors, other well-differentiated endocrine cell tumors, the gangliocytic paraganglioma, and /small cell carcinomas (poorly differentiated endocrine carcinomas). The term gastrinoma is reserved for G-cell tumors that produce hypergastrinemia and are the source of the Zollinger-Ellison syndrome.
