What Are Chromaffin Cells?

Pheochromaffin cells are secretory cells that make up the adrenal medulla. It is a mostly horn-shaped cell. There are a large number of chromaffin particles in the cytoplasm of adrenal medulla chromaffin cells. They appear as vesicles of different sizes under the electron microscope. These particles can be brown-yellow by potassium dichromate This reaction is called chromaffin reaction, so it is called chromaffin cell.

There are chromaffin cells in the human adrenal medulla and sympathetic ganglia, which have the function of secreting catecholamines such as epinephrine and norepinephrine. Pheochromocytoma is an endocrine disease originating from these parts. This tumor continuously or intermittently releases a large amount of catecholamines, causing persistent or paroxysmal hypertension and multiple organ functions and metabolic disorders. Most diseases, such as early diagnosis and treatment, can be cured; but in severe cases, the condition is dangerous, varied, and some are malignant tumors. The disease was thought to be rare in the past. In recent years, due to the improvement of the knowledge of the disease and the improvement of diagnostic technology, more cases have been found.
