Purpura Fulminans in a Patient With Septic Shock due to Escherichia coli Bacteremia With Emphysematous Pyelitis.

Purpura fulminans (PF) is a rapidly fatal disorder predominantly encountered in patients with an acquired deficiency of physiologic anticoagulants due to severe sepsis and septic shock with disseminated intravascular coagulation (DIC). This consumptive process eventually leads to widespread thrombosis, hemorrhagic necrosis, and gangrene. Rapid identification followed by aggressive management of the underlying etiology with a multidisciplinary team is critical to prevent long-term organ dysfunction, disability from amputation, and death. While bleeding is a common finding in DIC, anticoagulation must be considered if PF is present. We report a case of Escherichia coli--associated emphysematous pyelitis leading to bacteremia, septic shock, and PF with small- and medium-sized vessel thrombosis and acral ischemia.
