Summary
Purple glove syndrome is a rare complication of intravenous phenytoin, causing hand discoloration and swelling. Early findings suggest thrombosis may initiate this soft-tissue injury.
Area of Science:
- Dermatology
- Neurology
- Pathology
Background:
- Intravenous phenytoin is a common antiepileptic drug.
- Purple glove syndrome (PGS) is an uncommon but severe complication of IV phenytoin administration.
- Early histopathologic findings of PGS have not been previously described.
Observation:
- An 86-year-old man developed PGS after IV phenytoin administration.
- Early signs included pain, discoloration, and edema, progressing to vesiculobullous lesions.
- Biopsies revealed epidermal necrosis, ulceration, and microvascular thrombosis.
Findings:
- Histopathology of early-stage PGS shows epidermal necrosis and dermal microvascular thrombosis.
- Thrombosis is implicated in the initial pathogenesis of this soft-tissue injury.
- This study describes previously undocumented early-stage histopathologic features of PGS.
Implications:
- Understanding early pathogenesis can guide preventative strategies for IV phenytoin administration.
- Early recognition and intervention may mitigate the severity of purple glove syndrome.
- This research highlights the importance of careful IV administration techniques and monitoring for phenytoin-related complications.
