Glucagonoma syndrome with severe erythematous rash: A rare case report.

RATIONALE

Glucagonoma is a rare neuroendocrine tumor of the pancreas. Glucagonoma syndrome is often misdiagnosed as other skin lesions by clinicians due to a typical clinical sign of necrolytic migratory erythema (NME) with severe erythematous rash.

PATIENT CONCERNS

A 48-year-old female patient was admitted to our department because she presented with unclear recurrent severe erythematous rash. The patient was diagnosed as skin disease.

DIAGNOSES

Histopathologic examination revealed a pancreatic glucagonoma. Immnohistochemical staining of tumor tissue was positive for glucagon.

INTERVENTIONS

The distal pancreatectomy plus splenectomy was performed in 2017.

OUTCOMES

The skin lesions disappeared after surgery. She was followed up and showed no recurrence until now.

LESSONS

Clinicians should consider the diagnosis of glucagonoma according to the typical initial symptoms. Early diagnosis is very important to provide a better prognosis. A multidisciplinary approach is effective in patients with unresectable metastatic tumors.
