Abstract:
The purpose of the current manuscript is to familiarize the primary physician with the presentation of phenytoin hypersensitivity syndrome, and to discuss management options. A review of all admissions to the University of Mississippi Medical Center over a five year period revealed 4 cases of phenytoin hypersensitivity syndrome. These cases are presented and the phenytoin hypersensitivity syndrome, characterized most commonly by fever, cutaneous eruption and lymphadenopathy, is described. It is emphasized that the clinician must be aware of the syndrome and must recognize it on presentation. Theories regarding etiology and treatment options are discussed. It is recommended that all patients with symptoms of phenytoin hypersensitivity syndrome be hospitalized and that steroids be initiated.
