Abstract
A case is described that represents the only reported patient with glucagonoma syndrome and morbid obesity. The diagnosis of glucagonoma should be considered in any patient with the classic criteria despite weight gain. The criteria for diagnosis of glucagonoma are 1) the presence of a glucagon‐secrcting tumor, 2) hyperglucagonemia, and 3) the clinical manifestations of either necrolytic migratory erythema, glucose intolerance, or hypoaminoacidemia.
