Necrolytic migratory erythema: first symptom of a glucagonoma. A case report.

Necrolytic migratory erythema (NME) is a rare skin condition consisting of migrating areas of erythema with blisters that heal with hyperpigmentation. NME is a pathognomonic feature of a glucagonoma. When confronted with a xerosis cutis one should always exclude the possibility of a NME caused by a glucagonoma as demonstrated in this case report where the rash was wrongly attributed to an acrodermatitis enteropathica due to zinc deficiency. We describe a case of a glucagonoma with its classic features, diagnosis and treatment.
