A unique apudoma producing the glucagonoma and gastrinoma syndromes.

A patient is described who presented with a 10 year history of intermittent peptic ulcer symptoms and a 3 year history of an undiagnosed skin rash. Investigations indicated raised plasma levels of gastrin, glucagon and pancreatic polypeptide. A single tumour was localised to the pancreas and resected. The tumour had the typical histology of an apudoma, and contained cells which stained for gastrin, glucagon, pancreatic polypeptide and neurotensin.
