purple glove syndrome
,PGS
A rare, progressive, soft-tissue injury characterized by progressive edema and purple discoloration of the forearm and hand. It is caused by the extravasation of phenytoin into soft tissue. Adults over the age of 60 and those with a history of peripheral vascular disease receiving intravenous phenytoin are at increased risk for PGS, but the syndrome has also been documented in patients receiving high oral doses.
