Pheochromocytoma is a rare tumor arising from the chromaffin cells of the adrenal medulla [8].
Glomus cells of the carotid body, such as chromaffin cells of fetal adrenal medulla, are specialized in sensing local oxygen tension in mammals [9] and can undergo anatomical changes if exposed to chronic hypoxia [10].
The most studied chromogranin is CgA, which was first isolated from chromaffin cells of the adrenal medulla as a single polypeptide chain of 439 amino acids and 10 dibasic cleavage sites.
These are benign neoplasms composed of Schwann cells and ganglion cells that arise from the sympathetic ganglia; 20-30% arise in the adrenal medulla. (33) These lesions do not secrete hormones and are usually incidental findings.
A pheochromocytoma (PCC) is a rare catecholamine-secreting tumor that originates from the chromaffin cells of the adrenal medulla. First described by Frankel [1] in 1886, the estimated worldwide incidence of these tumors is 2 to 8 per million persons per year [2].
