Snuff-induced hypertension in pheochromocytoma

The dipping of snuff provoked paroxysmal hypertension that induced
myocardial ischemia in a 69-year-old woman with pheochromocytoma. The
diagnosis of her tumor was delayed by a report of a falsely low urine
metanephrine level, resulting from interference with the metanephrine assay
by meglumine present in the urine because of contrast coronary angiography
performed on the day of urine collection.
