Purple glove syndrome: a dreadful complication of intravenous phenytoin administration.

Purple glove syndrome is an uncommon but dreaded complication of intravenous phenytoin administration characterised by pain, oedema and purple-blue discolouration of the limb distal to the site of injection. We describe a 37-year-old gentleman having the characteristic purple glove appearance after phenytoin loading, and discuss the salient features of this syndrome highlighting the pathophysiological and preventive aspects.
