Iatrogenic necrolytic migratory erythema: a case report and review of nonglucagonoma-associated necrolytic migratory erythema.

Necrolytic migratory erythema is characterized by waves of irregular erythema in which a central bulla develops, and subsequently erodes and becomes crusted. It usually occurs in patients with an alpha-islet cell tumor of the pancreas. However, necrolytic migratory erythema has also been observed in patients without an associated glucagonoma. We describe a woman with iatrogenic necrolytic migratory erythema. She received intravenous glucagon for hypoglycemia associated with an insulin-like growth factor II-secreting hemangiopericytoma. After chemotherapy, she developed necrolytic migratory erythema. The characteristics of the previously reported patients with nonglucagonoma-associated necrolytic migratory erythema are reviewed. In patients with nonglucagonoma-associated necrolytic migratory erythema, the dermatosis-related conditions most commonly observed were celiac disease or malabsorption, cirrhosis, malignancy, and pancreatitis; less common conditions included hepatitis, inflammatory bowel disease, heroin abuse, and odontogenic abscess. Although the pathogenesis of necrolytic migratory erythema remains unknown, hyperglucagonemia appears to have had a causative role in the development of this dermatosis in our patient. Patients who develop necrolytic migratory erythema should be evaluated for the presence of a glucagonoma; if a glucagonoma is ruled out, evaluation for other conditions known to occur with necrolytic migratory erythema, such as liver disease, malabsorptive disorders, and nonislet-cell tumors is warranted.
