Adult pancreatic nesidioblastosis
Unusual presentations of a rare entity. Adult nesidioblastosis remains an uncommon and poorly understood condition creating both diagnostic and therapeutic dilemmas for clinicians. Despite the totipotent nature of hyperplastic pancreatic cells, nearly all accounts of nesidioblastosis described patients with symptoms of hypoglycemia. We herein describe two unique patients with adult nesidioblastosis with gastrin and pancreatic polypeptide secretion. Surgical resection rendered these two patients free of disease.
