Staphylococcal Purpura Fulminans: Report of a Case

摘要

Purpura fulminans (PF) is associated with several infections and most commonly with meningococcemia. However, there are only a few reports of this entity in association with toxic shock syndrome toxin-1-producing Staphylococcus aureus. We report a 53-year-old man who presented with fever, progressive hemodynamic instability, multiorgan failure, and thrombocytopenia following lobectomy for a solitary lung metastasis from rectal adenocarcinoma. He developed progressive generalized eruption of nonblanching red, purple, and black macules, papules, and plaques on the trunk and extremities consistent with PF. He died on postadmission day 3. Autopsy examination revealed purulent pleural exudate, which grew toxic shock syndrome toxin-1-producing S. aureus. Premortem and autopsy skin biopsies demonstrated epidermal necrosis, subepidermal bullae, and fibrin thrombi within small cutaneous vessels with minimal perivascular lymphocytic inflammation and without accompanying vasculitis. With this case report, we would like to draw attention to the fact that staphylococcal toxic shock syndrome-associated PF may be highly underrecognized and much more common than reflected in the literature.
