The primary [[physiology|physiological]] effect of glucagonoma is an overproduction of the [[peptide]] hormone [[glucagon]], which enhances [[blood glucose]] levels through the activation of [[catabolism|catabolic]] processes including [[gluconeogenesis]] and [[lipolysis]]. Gluconeogenesis produces [[glucose]] from [[protein]] and [[amino acid]] materials; lipolysis is the breakdown of [[adipose tissue|fat]]. The net result is hyperglucagonemia, decreased blood levels of [[amino acid]]s (hypoaminoacidemia), [[anemia]], [[diarrhea]], and weight loss of 5-15 [[kilogram|kg]].

Overview

History and Symptoms

  • Necrolytic migratory erythema (NME) is a classical symptom observed in patients with glucagonoma and is present in 80% of cases. Associated NME is characterized by the spread of erythematous blisters and swelling across areas subject to greater friction and pressure, including the lower abdomen, buttocks, perineum, and groin.
