Neuroendocrine lesions of the thyroid are rare. The most common types are medullary thyroid carcinomas (MTCs) and C-cell hyperplasia. MTCs originate from thyroid parafollicular cells that secrete calcitonin which serves as a serum marker of MTCs. Here, the rare case of a calcitonin-negative neuroendocrine tumor (NET) derived from follicular lesions of the thyroid is described. A 34-year-old man presented at our hospital for the surgical management of an incidental thyroid nodule that was observed on an ultrasound sonography (USG) of the neck. Initially, USG-guided aspiration cytology was performed, and a MTC was suspected. The expressions of thyroglobulin and thyroid transcription factor-1, which are thyroid follicular cell markers, and synaptophysin and chromogranin A, which are neuroendocrine markers, was confirmed following surgical pathology. However, the staining of calcitonin, a marker of MTCs, was not observed. A nonmedullary NET of the thyroid is uncommon, and the distinction between calcitonin-negative NETs and MTCs of the thyroid may be important due to differences in their clinical courses and management.

AbstractAbstract PDF
Nesidioblastosis is characterized by a diffuse proliferation of islet cells arising from pancreatic ducts and is the most common cause of hyperinsulinemic hypoglycemia in newborns and infantile. It is exceedingly rare in adults and no concensus regarding its diagnosis and management is available. We herein describe an elderly man with fasting hypoglycemia, inappropriate insulin hypersecretion. And pathologic examination of his pancreas revealed the characteristic finding of nesidioblastosis confirmed by immunohistochemical stain.
