[Glucagonoma revealed by necrolytic migratory erythema].

Malignant glucagonoma is rare and frequently associated with cutaneous manifestations such as necrolytic migratory erythema. We report the case of a patient who developed necrolytic migratory erythema 12 months before the diagnosis of malignant glucagonoma. Skin involvement recovered after surgical resection of a primitive pancreatic tumor and hepatic and ileal metastasis.
