Overview

Glucagonoma must be differentiated from certain skin lesions (acrodermatitis enteropathica, psoriasis, pellagra, eczema) and other causes of hyperglucagonemia (infection, diabetes mellitus, Cushing syndrome, renal failure, acute pancreatitis, severe stress, and prolonged fasting).

Differentiating Glucagonoma from other Disease

Glucagonoma must be differentiated from certain skin lesions in which necrolytic migratory erythema can be found and other causes of hyperglucagonemia:

Glucagonoma	The first peak for the development of psoriasis occurs between 20 years to 35 years and the second peak is between 40 years to 65 years of life. Patients with early disease onset often have a positive family history of psoriasis, frequent association with histocompatibility antigen (HLA)- Cw6, and more severe disease. Those with onset after the age of 40 usually have a negative family history and a normal frequency of the HLA- Cw6 allele.[2] A typical patient of psoriasis will present with a history of a long-term erythematous scaly area with ocular and joint involvement depending upon the clinical subtype and chronicity of the disease. There may be multiple relapses and remissions. Past medical history of the patient may include viral or bacterial infection, diabetes, hypertension, chronic kidney disease and/or obesity due to an association of psoriasis with these conditions.[3] A social history of the patient may indicate smoking, excessive alcohol consumption and/or a recent stressful event if life associated with an acute exacerbation of psoriasis.[4]
