title: Phenytoin hepatotoxicity masked by corticosteroids.
abstract: The association of phenytoin and liver toxicity is well documented. This article describes a patient who underwent a transsphenoidal resection of a pituitary tumor who developed phenytoin-induced hepatotoxicity that was masked by the simultaneous administration of corticosteroids for treatment of cerebral edema. In a patient receiving both medications, the systemic manifestations of the hypersensitivity to phenytoin may go unrecognized, leading to delayed identification of a potentially lethal complication of this commonly prescribed anticonvulsant.
