Doctor's answer:
Pheochromocytoma originates from chromaffin cells. During the embryonic period, the distribution of chromaffin cells is related to the sympathetic ganglia of the body. As the pig matures, most chromaffin cells degenerate, and the remaining part forms the adrenal medulla. Therefore, most pheochromocytomas occur in the adrenal medulla.
