title: Neurocutaneous melanosis presenting as chronic partial epilepsy.
abstract: BACKGROUND
  Neurocutaneous melanosis (NCM) is a rare neurocutaneous syndrome characterized by the presence of multiple congenital melanocytic nevi (CMN) and the proliferation of melanocytes in the central nervous system, usually involving the leptomeninges. Chronic partial epilepsy as a sole manifestation is rare in NCM.
  
  
  METHODS
  A 32-year-old man suffering from chronic partial epilepsy presented with multiple CMN on his trunk and scalp. Brain MRI demonstrated a focal lesion in the right amygdala that was consistent with interictal epileptiform discharges in the right temporal region on electroencephalography (EEG). An anterior temporal lobectomy was performed, and the pathology investigation revealed numerous melanophages in the amygdala. The patient was seizure-free after surgery.
  
  
  CONCLUSIONS
  We report a patient with NCM presenting as chronic partial epilepsy who was successfully treated by anterior temporal lobectomy.
