Salt-and-pepper chromatin
Appearance
In pathology, salt-and-pepper chromatin, also salt-and-pepper nuclei and stippled chromatin, refers to cell nuclei that demonstrate granular chromatin (on light microscopy).[1]
Salt-and-pepper chromatin is typically seen in endocrine tumours such as medullary thyroid carcinoma, neuroendocrine tumours[2] and pheochromocytoma.[3]
