摘要To the Editor:Pheochromocytomas are rare neuroendocrine tumors that originate from the chromaffin cells in the adrenal glands or associated sympathetic ganglia.[1] To the best of our knowledge,malignant pheochromocytoma is extraordinarily rare,with a frequency of 0.2-0.9 case per 1,000,000 individuals per year,and there is obvious shortage of clinical reports on metastatic pheochromocytoma to the spine.Thus,it can be difficult to diagnose and may result in devastating consequences upon mismanagement.[2]
