Glucagonoma syndrome: A case report.

Area of Science:

• Endocrinology
• Dermatology
• Oncology

Background:

• Glucagonoma syndrome comprises glucagon-secreting tumors, diabetes mellitus, and necrolytic migratory erythema (NME).
• NME is frequently the initial clinical manifestation, but glucagonoma's rarity leads to diagnostic delays and disease progression.
• Delayed diagnosis can result in prolonged and ineffective treatments, such as corticosteroids for misdiagnosed skin conditions.

Purpose of the Study:

• To present a case of glucagonoma syndrome with characteristic NME.
• To emphasize the diagnostic challenges and delayed treatment associated with this rare condition.
• To illustrate the typical features of glucagonoma syndrome to enhance clinical recognition and management.

Main Methods:

• Case report detailing a patient with NME misdiagnosed for two years.
• Review of clinical presentation, diagnostic process, and treatment outcomes.
• Surgical intervention involving the removal of a pancreatic body tumor.

Main Results:

• The patient presented with a typical NME skin rash, initially misdiagnosed and treated with corticosteroids.
• Surgical removal of the pancreatic glucagon-secreting tumor led to rapid resolution of NME symptoms.
• This outcome underscores the direct link between the tumor and the dermatological and metabolic manifestations.

Conclusions:

• Glucagonoma syndrome requires high clinical suspicion, especially with characteristic NME.
• Early diagnosis and surgical management of the glucagon-secreting tumor are crucial for effective treatment.
• Recognizing the typical presentation can prevent diagnostic delays and improve patient outcomes.
