Melanotic differentiation in dysembryoplastic neuroepithelial tumor

Dysembryoplastic neuroepithelial tumor (DNT) is an uncommon intracranial tu mor which is usually encountered in patients with medically intractable com plex partial seizures of temporal lobe origin. Melanotic differentiation in a DNT has not been reported previously Herewith we report a case of DNT wi th unique melanotic differentiation in a 23-year-old female who presented w ith medically intractable epilepsy. She underwent craniotomy and tumor deco mpression with a good outcome. We present the histopathological features of DNT with melanotic differentiation and discuss its prognostic significance .
