Abstract

Pheochromocytoma is a catecholamine producing turnor and raise with less than 0.1% of hypertensive patients. It is developed, most commonly, in sporadic pheochromocytoma or multiple endocrine neoplasia type 2. Therefore, when hypercalcitoninemia is found in a patient with pheochromocytoma, the possibility of multiple endocrine neoplasia type 2 or the ectopic secretion of calcitonin must be considered. Recently we experienced a 45 year old male patient with sporadic pheochrornocytoma. He also had hypercalcitoninemia and normocalcemia. After the removal of pheochromocytoma, serum calcitnnin level returned to normal. Secretion of calcitonin was confirmed by immunohisto- chemical stain.

Key Words: Hypercalcitoninemia, Pheochromocytoma
