Purple glove syndrome following intravenous phenytoin administration

Abstract

Purple glove syndrome (PGS) is a rare complication of intravenous phenytoin use that typically presents with pain, edema, and discoloration at the injection site that spreads to the distal limb. Several risk factors have been associated with the development of PGS; however, the etiology remains unknown. We present a case of PGS and briefly review the current understanding of this syndrome.
