Abstract

Background:

Necrolytic migratory erythema (NME) is most commonly a paraneoplastic condition. It is the dermatologic manifestation classically associated with glucagonoma pancreatic neuroendocrine tumour. Glucagonoma syndrome has been defined by the constellation of secreting tumour associated with overproduction by the α-cells in the pancreatic islets of Langerhans, abnormally elevated blood level of glucagon, and skin findings of NME.

Objective:

Although rare, all dermatologists must know and recognise NME promptly to request useful investigations for the diagnosis of this characteristic neuroendocrine tumour.

Methods and Results:

We report a case of a middle-aged woman seen in our dermatology clinic with longstanding skin findings suggestive of NME revealing a glucagonoma. Surgical removal was associated with complete resolution of the cutaneous and systemic features.

Conclusion:

NME is often the first clinical finding of an occult neuroendocrine pancreatic neoplasia. Dermatologists must be aware of this condition since they can be the first physician to suspect it and allow multidisciplinary management, which influences the prognostic value. Surgical removal is the first-line therapy if early diagnosis is done before liver metastases occur.
