Nesidioblastosis is a term that describes multifocal hyperplasia of all panereatic cell components and is characterized primarily by their disorganization and proliferation throughout the entire panaeas. Adult onset nesidioblastosis is an extremely rare entity associated with hypersecretion of insulin. The authors have recently experieneed a case of nesidioblastosis in an adult. A 41-year old man was admitted due to interrnittenr hypoglycemic symptoms, that had been relieved by carbohydrate ingestion. Hyperinsulinemic hypoglycemia was documented during prolonged fast. Under the presumptive diagnosis of insulinoma, abdominal CT, celiac angiogram and percutaneous transhepatic portal venous sampling were done but we could not find any definitive mass. Eight-five percent of the panacas was removed. Pathologic examination of the resected pancreas revealed irregularly sized islets and scattering of small endocrine cell clusters throughout the acinar tissue and ductuloinsular complex.
Key Words: Nesidioblastosis, hyperinsulinemic hypoglycemia
