Abstract

A 23-year-old man with circulatory shock associated with severe sepsis and congestive heart failure with an ejection fraction of 10% resulting in anasarca and multiorgan failure was admitted to our hospital's intensive care unit. Hours after admission, he developed a rash on his left inner thigh, which was later diagnosed as purpura fulminans (PF). Blood cultures were consistent with Klebsiella pneumoniae bacteremia, with community-acquired pneumonia being the possible source. PF is a rare and difficult-to-diagnose entity characterized by dysregulated hemostasis that is often associated with poor prognosis and fatal outcomes. To our knowledge, there are limited reports in the literature on K. pneumoniae as a cause of PF. Given the rarity of this presentation, this case will serve as an opportunity to report and discuss the pathophysiology of this disease for the benefit of physicians.
