Abstract
Lymphadenomegaly associated with antiepileptic drugs is well documented; however,
severe lymphadenopathy mimicking a neoplasm is a rare adverse event associated with
antiepileptic drugs. It is usually characterized by a large cervical mass associated
with fever, weight loss, skin rash, and abnormal complete blood count (atypical lymphocytes,
eosinophilia, and abnormal neutrophil count). In this case report, we described a
child with severe bilateral cervical lymphadenomegaly associated with ethosuximide,
in which excisional biopsy of the enlarged nodes was needed to establish the final
diagnosis. Prognosis was excellent after drug discontinuation.
