title: [Arterial hypertension due to mercury intoxication with clinico-laboratorial syndrome simulating pheochromocytoma].
abstract: A 17 year-old boy was admitted to the hospital because of severe hypertension (200/130 mmHg), headache, irritability, and sweating. Initial biochemical tests suggested pheochromocytoma, being treated with nifedipine, clonidine and propranolol. However, with report of exposure to mercury vapor, twenty-four-hour urine screening and measurement of blood mercury confirmed intoxication. The patient underwent courses of chelation therapy with dimercaprol (BAL) and penicillamine with remission of symptoms and normalization of blood pressure after 2 months. This case has relevance for current practice reflecting similarity between mercury intoxication and hypertension secondary to pheochromocytoma.
