嗜铬细胞瘤大约90%发生在肾上腺髓质,发生于肾上腺以外的嗜铬细胞瘤称为异位嗜铬细胞瘤,临床上较少见,多数发生于腹部,发生于胸腔者更为罕见。因其可引起高血压,手术中血压波动剧烈,若术前未做出诊断,手术风险极大[1]。现就作者遇到的2例胸腔异位嗜铬细胞瘤并结合国内文献进行 About 90% of pheochromocytoma occurs in the adrenal medulla, pheochromocytoma occurs outside the adrenal gland called ectopic pheochromocytoma, clinically rare, the majority occur in the abdomen, occur in the pleural cavity is even more rare. Because it can cause high blood pressure, blood pressure fluctuations during surgery, if not diagnosed before surgery, the surgical risk is great [1]. Now the author encountered 2 cases of thoracic heterotopic pheochromocytoma combined with domestic literature
