Clinical features<unk>  features a characteristic skin eruption of red patches with irregular borders, intact and ruptured vesicles, and crust formation. It commonly affects the limbs and skin surrounding the lips, although less commonly the abdomen, perineum, thighs, buttocks, and groin may be affected. Frequently these areas may be left dry or fissured as a result. All stages of lesion development may be observed synchronously. The initial eruption may be exacerbated by pressure or trauma to the affected areas. Associated conditions William Becker first described an association between<unk>  and glucagonoma in 1942 and since then,<unk>  has been described in as many as 70% of persons with a glucagonoma.<unk>  is considered part of the glucagonoma syndrome, which is associated with hyperglucagonemia, diabetes mellitus, and hypoaminoacidemia. When<unk>  is identified in the absence of a glucagonoma, it may be considered "pseudoglucagonoma syndrome". Less common than<unk>  with glucagonoma, pseudoglucagonoma syndrome may occur in a number of systemic disorders: * Celiac disease * Ulcerative colitis * Crohn's disease * Hepatic cirrhosis * Hepatocellular carcinoma * Lung cancer, including small cell lung cancer * Tumors that secrete insulin- or insulin-like growth factor 2 * Duodenal cancer
