title: [A clinical review of 19 patients with pheochromocytoma].
abstract: Nineteen cases of pheochromocytoma were experienced at our department between 1979 and 1990. Nine patients were males and 10 females with an average of 42.4 years old. In 18 patients the tumor was located in the adrenal gland (9 in right, 5 in left and 4 in bilateral adrenal gland), while in one patient whose original tumor had been resected 15 years earlier, the tumor had recurred in the extra-adrenal gland and was surgically extirpated revealing a malignant pheochromocytoma by histological examination. Hypertension was seen in 16 patients; 14 had paroxysmal and 2 had sustained hypertension. In 3 patients, hypertension was not observed. Familial pheochromocytoma was seen in 5 patients. Three patients had Sipple syndrome. Computed tomographic scan and magnetic resonance imaging were very useful techniques in preoperatively localizing the tumor. Even in the cases treated with alpha- or beta-blocker agents preoperatively, significant hypotension was observed immediately after resection of the tumor and treatment with norepinephrine or rapid blood transfusion or both was needed. Although meticulous care with alpha- and beta-blockers is important, surgical treatment of pheochromocytoma should spare the surgeon of unnecessary anxiety.
