title: Pheochromocytoma associated with adrenocortical adenoma: case report and literature review.
abstract: The case of a 60-year-old woman with pheochromocytoma and concomitant adrenocortical adenoma in the same gland is presented. She complained of episodic headache, palpitation, nausea, vomiting and sweating. Physical examination revealed that the patient has generalized obesity, wet skin and paroxysmal hypertension, but no signs of Cushing's syndrome. Elevated levels of urinary noradrenaline, adrenaline and total metanephrine were sequentially observed. In addition, urinary 17-OHCS was also slightly elevated, but plasma cortisol was normal and suppressed after oral administration of 0.5 mg of dexamethasone. Abdominal echography and CT scanning demonstrated a left adrenal tumor, which took up both 131I-meta-iodobenzylguanidine and 75Se-scintadoren in the same region. A left adrenalectomy was performed and the tumor was found to consist of two parts, pheochromocytoma (2.5 X 2.5 X 2.5 cm) and cortical adenoma (2.5 X 3 X 5 cm). A total of 23 reported cases showing evidence of hyperfunction of the adrenal cortex and the medulla were noted. So far as we know, this patient was the second case of pheochromocytoma with adrenocortical adenoma in Japan.
