Phenytoin-induced lymphadenopathy appearing as a nasopharyngeal malignant neoplasm
E. L. Treyve and L. G. Duckert
A case of phenytoin sodium-induced lymphadenopathy appeared as a
nasopharyngeal malignant neoplasm with regional metastases. Cervical
lymphadenopathy is a lesser-known drug reaction that is produced by
anticonvulsant therapy; under some circumstances, this condition may be
confused with head and neck malignant neoplasms. To date, phenytoin-induced
nasopharyngeal lymphadenopathy has not previously been reported in the
literature. A review of the medical literature provides some interesting
facts about the syndrome. A familiarity with this potential complication of
anticonvulsant therapy may expedite early diagnosis and appropriate patient
treatment.
