Necrolytic Migratory Erythema: Complete Healing after Surgical Removal of Pancreatic Carcinoma.

Necrolytic migratory erythema is considered an obligatory cutaneous paraneoplastic sign associated with glucagonoma. Glucagonoma syndrome is defined by the presence of an alpha-cell secreting tumor of the pancreas, elevated levels of glucagon, and a characteristic rash called necrolytic migratory erythema. Although necrolytic migratory erythema is a specific finding in glucagonoma syndrome, it may occur in other settings, unassociated with an alpha-cell pancreatic tumor (pseudoglucagonoma syndrome).
