A case of Parry–Romberg syndrome and alien hand

Abstract Parry–Romberg syndrome (PRS) is a rare condition characterised by progressive hemi-facial atrophy. Here we present a PRS case with alien-hand syndrome, which has not previously been described in adult onset disease. On the basis of the presumed auto-immune pathology of PRS we justify the treatment strategy we successfully used in this patient. A review of the literature was extensively done for understanding the history of alien hand sign over the years.
