Resolution of necrolytic migratory erythema with somatostatin analogue in a patient diagnosed with pancreatic glucagonoma

Abstract

A 70-year-old man reported progressive weight loss, fatigue and a generalised rash. The rash was consistent with necrolytic migratory erythema, further investigations were performed and the patient was diagnosed with a mass in the tail of the pancreas, in keeping with a localised glucagonoma. Somatostatin analogue therapy was started for symptom control, leading to complete resolution of the skin rash and an improvement in constitutional symptoms. Subsequently, the pancreatic lesion was excised, and pathology assessment confirmed the diagnosis of well-differentiated neuroendocrine tumour with high expression of glucagon compatible with glucagonoma.
