WebNov 10, 2014 · The neural crest lineage is extremely diverse and widespread. Tumor types range from medullary thyroid carcinoma in the thyroid C cells to pheochromocytoma in the chromaffin cells of the adrenal medulla.

Figure 2 Open in figure viewer PowerPoint WebThe adrenal medulla is part of the sympathetic nervous system, which arises from cells of the neural crest during embryonic development. Storage granules which stain brown with chromic acid due to oxidation of catecholamines to melanin give the cells which contain them the name chromaffin or pheochrome cells.
