[Partial benign crises in adolescence].

The aim of this paper is to present the case of teenage patient with partial seizures fulfilling the criteria of benign partial seizures of adolescence. A 16-year-old male patient had two seizures with a sensory-motor "march" that evolved into a secondarily generalized tonic-clonic seizure on the same day. Several weeks before this event he had had several simple partial sensory seizures. The patient had no previous history of seizures and there was no family history of epilepsy. The neurological examination, EEG and magnetic resonance imaging were normal. The patient was treated with antiepileptic monotherapy during two years. The treatment was gradually tapered and withdrawn over the following six months. He has had no recurrences during the five years of follow-up. The early diagnosis of this entity has the significant prognostic and therapeutic repercussions.
