嗜铬细胞瘤绝大多数发生于肾上腺髓质,少数发生于肾上腺外,诸如颈动脉体,主动脉旁的交感神经节,嗜铬体(腹主动脉分叉处)等。偶尔也可以在膀胱、脾、卵巢、睾丸等部位发生。笔者近年来迂见肾上腺外嗜铬细胞瘤2例,1例位于膀胱壁,1例位于腹主动脉分叉处,现报告如下。 The vast majority of pheochromocytoma occurs in the adrenal medulla, and a few occur outside the adrenal gland, such as the carotid body, the sympathetic ganglion next to the aorta, and the chromite body (bifurcation of the abdominal aorta). Occasionally, it can also occur in the bladder, spleen, ovary, testicles and other parts. In recent years, the author has seen 2 cases of adrenal pheochromocytoma, 1 in the bladder wall and 1 in the abdominal aortic bifurcation. The report is as follows.
