Glucagonoma syndrome: case report and literature review.

The glucagonoma syndrome is characterized by dermatitis, glucose intolerance, hypoaminoacidemia, and hyperglucagonemia secondary to an alpha-cell tumor of the pancreas. Other clinical features include anemia, glossitis, and weight loss. A 62-year-old woman with the syndrome sought medical attention for a chronic dermatitis. A skin biopsy was suggestive of necrolytic migratory erythema. A glucagonoma was surgically removed from the tail of the pancreas. Review of the literature indicates that 56 proven and 33 probable cases of glucagonoma syndrome have been reported.
