What does purpura fulminans look like?

The initial appearance of purpura fulminans lesions is of well-demarcated erythematous lesions which progress rapidly to develop irregular central areas of blue-black haemorrhagic necrosis. Advancing areas of necrosis are often surrounded by a thin border of erythema that fades into adjacent unaffected skin.

What are purpura fulminans?

Purpura fulminans (PF) is a haematological emergency in which there is skin necrosis and disseminated intravascular coagulation. This may progress rapidly to multi-organ failure caused by thrombotic occlusion of small and medium-sized blood vessels.

How common is purpura fulminans?

Each form of purpura fulminans has a different prevalence. The hereditary neonatal form with severe protein C deficiency occurs in about 1:1,000,000 live births. [2]Acute infectious purpura fulminans can be seen in up to 10% to 20% of patients who develop meningococcal septicemia.

What is Purpura sepsis?

Sepsis-associated Purpura fulminans (SAPF) is a rare life-threatening condition. It is characterized by multiple skin lesions which rapidly progress to necrosis and gangrene. SAPF is a manifestation of widespread clot formation in small blood vessels which emerges secondarily to severe bacterial and viral infections.

What causes purpura Fulminans?

The most common cause of acute infectious purpura fulminans is meningococcus, though streptococci, varicella-zoster virus, Gram-negative bacilli, staphylococci, Rickettsia species, and measles virus have also been associated with this form of purpura fulminans.

What does purpura spots look like?

Purpura occurs when small blood vessels burst, causing blood to pool just under the skin. They appear as small, reddish-purple spots just beneath the skin’s surface.

What is purpurpura fulminans (PRF)?

Purpura fulminans is the acute onset of often rapidly progressing cutaneous hemorrhage and necrosis caused by dermal vascular thrombosis and disseminated intravascular necrosis.   It occurs in 3 clinical settings:

How long does it take for purpura fulminans to heal?

Purpura fulminans lesions, once established, often progress within 24 to 48 hours to full-thickness skin necrosis or soft-tissue necrosis. Once purpura fulminans lesions progress to full-thickness skin necrosis, healing takes between 4–8 weeks and leaves large scars.

Which histologic findings are characteristic of purpura fulminans?

Purpura fulminans is characterized by disseminated purpuric lesions often associated with bullae and necrosis. The histopathology of these lesions reveals diffuse cutaneous microthrombi with surrounding hemorrhage. Diffuse thrombosis, including stroke, retinal infarcts, limb gangrene, and DIC, can occur in purpura fulminans.

What are the signs and symptoms of purpura fulminans in sepsis?

Purpura fulminans in severe sepsis typically develops in the distal extremities and progresses proximally or appears as a generalised or diffuse rash affecting the whole body surface. In cases of severe inheritable protein C deficiency, purpura fulminans with disseminated intravascular coagulation manifests within a few hours or days after birth.
