Phenytoin-induced lymphadenopathy appearing as a nasopharyngeal malignant neoplasm.
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.
