title: Cystic pheochromocytoma with inadvertent needle biopsy and glucagon administration.
abstract: Needle aspiration biopsy and glucagon administration are considered contraindicated in catecholamine-producing tumors. We report a patient with an unusual cystic pheochromocytoma who inadvertently received intravenous glucagon and who underwent percutaneous needle biopsy with no apparent adverse effects.
