Gastrinomas are most classically associated with which syndrome?

• A. Zollinger-Ellison syndrome
• B. MEN syndrome
• C. Peptic ulcer disease
• D. Gastric cancer

Answer: (A)

Gastrinomas drive excessive gastrin production, which in turn causes marked gastric acid hypersecretion. This combination produces the clinical syndrome known as Zollinger-Ellison, characterized by severe and recurrent peptic ulcers (often distal to the stomach and in atypical locations) and can include diarrhea from acid-related effects on the small intestine. Because the gastrinoma leads to this specific clinical picture, Zollinger-Ellison syndrome is the classic association. It’s worth noting that gastrinomas can occur in the setting of MEN1 (multiple endocrine neoplasia type 1), but the traditional, defining syndrome linked to the tumor’s effects is Zollinger-Ellison. Peptic ulcer disease can result from many causes, and gastric cancer is not the characteristic syndrome associated with gastrinomas.
