[Glucagon producing adenomatosis of Islands of Langerhans with polyendocrine symptoms].
A patient in whom Cushing syndrome had been diagnosed at the age of 23 was found 14 years later to have subclinical diabetes mellitus, subcutaneous calcified fat tissue necroses, and hypergastrinemia suggesting Zollinger-Ellison syndrome. Histopathologic investigation revealed pancreatic adenomatosis of the glucagon producing A2-cells with accompanying B-cell hyperplasia, and hyperplasia of the adrenal cortex. The origin of the increased serum gastrin concentration in this patient is not yet known. The significance of A2-cell proliferation in Zollinger-Ellison syndrome and and in multiple endocrine adenomatosis is discussed.
