Presentation and outcome of purpura fulminans associated with peripheral gangrene in 12 patients at Mayo Clinic - 19/08/11
Abstract |
Background |
Dermatologists may be called to assist in the diagnosis and management of purpura fulminans.
Methods |
This retrospective case series details the clinical presentation and outcomes of patients presenting with purpura fulminans associated with peripheral gangrene between 1989 and 2004.
Results |
All 12 patients presented with sudden onset of purpuric patches and evolving gangrene of the extremities in association with a shock syndrome (hypotension, oliguria). Eleven patients had disseminated intravascular coagulation. The cause of purpura fulminans was infectious in 9 patients, surgical in two, and cancer in one. Three patients died (25%) within a week of onset of purpura fulminans. Of the 9 surviving patients, 8 required amputation of at least one limb. Four patients required amputation of all 4 limbs.
Limitations |
Retrospective study design, varying clinical descriptions, and potential referral bias are limitations.
Conclusion |
Purpura fulminans in association with symmetric peripheral gangrene is an ominous clinical presentation.
