Hemorrhagic necrosis of pheochromocytoma is an unusual, but life-threatening complication. Sudden onset of abdominal pain in a patient with pheochromocytoma suggests the occurrence of homorrhagic necrosis of the tumor. The patient may be hypertensive or in shock. The hemorrhagic necrosis produces shock by acute cessation of catecholamine release. We have recently seen a 13 years old boy with von Hippel syndrome, who was suspected og having a residual extra-adrenal tumor after the excision of bilateral pheocromocytoma and complained of acute abdominal pain accompanied by high blood pressure. The pain was relieved with conservative therapy. Thereafter, however, the blood pressure decreased to a normal level with marked improvement in hypertensive symptoms. Plasma norepineohrine dropped from 8.62 ng/ml during the spisode to 0.55 ng/ml after it. Clinicopathological features of hemorrhagic necrosis of pheochromocytoma were discussed.
