Purple glove syndrome (PGS) is a poorly understood skin disease in which the extremities become swollen, discoloured and painful. PGS is potentially serious, and may require amputation. PGS is most common among elderly patients and those receiving multiple large intravenous doses of the epilepsy drug phenytoin. Compartment syndrome is a complication of PGS.
Treatment
Doctors recommend discontinuing the use of phenytoin. The application of heat can help to relieve pain. Oral phenytoin can also result in development of purple glove syndrome.
