Final answer:
Zollinger-Ellison syndrome occurs in patients with severe peptic ulceration and evidence of a gastrinoma. It leads to the overproduction of stomach acid.
Step-by-step explanation:
The syndrome described in the question is called Zollinger-Ellison syndrome. It is a rare condition that occurs in patients with severe peptic ulceration and evidence of a gastrinoma. Gastrinomas are tumors that secrete excessive amounts of gastrin, a hormone that stimulates the production of stomach acid. Zollinger-Ellison syndrome leads to the overproduction of stomach acid, which can cause severe peptic ulcers.
