Kufs' disease presenting as late-onset epilepsia partialis continua.

A 64-year-old woman, who had no personal or family history of neurologic diseases, had an 18-month history of epilepsia partialis continua (EPC) associated with a moderate intellectual deterioration and subtle extrapyramidal rigidity. There was no photosensitive response. A thorough laboratory investigation was unremarkable. A biopsy of the rectal mucosa revealed abundant fingerprint profiles diagnostic of Kufs' disease (KD). Our case expands the clinical picture of KD and suggests that such a diagnosis should be considered in adult-onset EPC.
