These causes of retiform purpura, in addition to bacterial or fungal sepsis, disseminated intravascular coagulation, purpura fulminans, and catastrophic antiphospholipid syndrome, are important diagnoses with potential for morbidity and mortality. Important aspects in the pathophysiology, patient demographics and risk factors, updates in the diagnostic workup, histopathology, and treatment of these specific conditions are discussed.Le texte complet de cet article est disponible en PDF.
