Glucagonoma syndrome

Glucagonoma syndrome is a rare disease in which necrolytic migratory erythema is often one of the early symptoms. Weight loss and diabetes mellitus are two other characteristics of this syndrome. Necrolytic migratory erythema is typically characterized on skin biopsies by necrolysis of upper epidermis with vacuolated keratinocytes. Persistent hyperglucagonemia results in excessive stimulation of basic metabolic pathway which in turn results in diabetes mellitus at the expense of tissue glycogen stores. Deficiencies of various essential nutrients and vitamin B lead to dermatosis. Due to rarity of glucagonoma, it is quite difficult to diagnose this syndrome at early stages
