Description

Chromogranin A is localized in secretory granules of neurons and endocrine cells in tissues, including pituitary, adrenal medulla, thyroid, pancreatic islets and gastrointestinal tract. Neuroendocrine cells exhibit a fine granular immunoreactivity to Anti-Chromogranin A. It is widely recognized that co-expression of keratins and chromogranin A implies a neuroendocrine lineage. High expression of Chromogranin A and negative staining with Anti-Keratin is a possible indication of paraganglioma. Positive staining for Chromogranin A and neuron-specific enolase is representative of neuroendocrine neoplasms. Many pituitary adenomas and prolactinomas stains positively for Chromogranin A.
