Neuron-specific enolase (NSE), an isomer of glycolytic enzyme enolase, is found exclusively in neuroendocrine cells and in neuroendocrine tumors in a considerably large quantity. Circulating levels of serum NSE were measured by radioimmunoassay in 24 normal adults, 23 patients with benign pheochromocytoma, three patients with malignant pheochromocytoma, and seven patients with medullary thyroid carcinoma. The mean serum NSE in normal adults was 5.8 +/- 1.3 ng/ml (mean +/- standard deviation [SD], and the range was 3.8 to 8.9 ng/ml). It also was normal in patients with benign pheochromocytoma (5.7 +/- 1.8 ng/ml; range, 2.2 to 9.3 ng/ml). However, serum NSE was elevated significantly (17.2 +/- 7.2 ng/ml; range, 10.4 to 27.3 ng/ml) in all three patients with malignant pheochromocytoma (P less than 0.01). In patients with medullary thyroid carcinoma the serum NSE remained within normal limits (5.5 +/- 1.7 ng/ml; range, 3.9 to 8.2 ng/ml). These results suggest that serum NSE might be a useful marker for screening of malignant pheochromocytoma.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D010673	Pheochromocytoma	A usually benign, well-encapsulated, lobular, vascular tumor of chromaffin tissue of the ADRENAL MEDULLA or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of EPINEPHRINE and NOREPINEPHRINE, is HYPERTENSION, which may be persistent or intermittent. During severe attacks, there may be HEADACHE; SWEATING, palpitation, apprehension, TREMOR; PALLOR or FLUSHING of the face, NAUSEA and VOMITING, pain in the CHEST and ABDOMEN, and paresthesias of the extremities. The incidence of malignancy is as low as 5% but the pathologic distinction between benign and malignant pheochromocytomas is not clear.
