An autopsy case of pancreatic and ectopic nesidioblastosis.
We report an autopsy case of pancreatic and ectopic nesidioblastosis. A five-month-old Japanese girl was born at 35 weeks gestation, and showed clinical symptoms of hyper-insulinemic hypoglycemia before death. At autopsy a tumorous nodule was observed at the portion of the jejunum, 90 cm from Treitz's ligament. The nodule measured 30 x 20 x 20 mm. The ectopic pancreas, also revealed nesidioblastosis histologically. Immunohistologically, both nesidioblastoses were stained positive for chromogranin A, insulin, glucagon and somatostatin. The proliferating cell nuclear antigen (PCNA) and Ki-67 indices were less than 4% in the nesidioblastosis. To our knowledge, this is the first reported case of nesidioblastosis demonstrating proliferating activity with PCNA and Ki-67, and is the third reported case of nesidioblastosis arising in the pancreas and ectopic pancreas.
