Fulminans Purpura due to Morganella morganii

Area of Science:

• Dermatology
• Infectious Diseases
• Critical Care Medicine

Background:

• Purpura fulminans (PF) is a severe dermatological manifestation linked to disseminated intravascular coagulation and thrombosis.
• The most frequent forms of PF are idiopathic or infectious, often associated with Neisseria meningitidis or Streptococcus pneumoniae.
• This case highlights a rare presentation of PF secondary to Morganella morganii bacteremia.

Purpose of the Study:

• To report a case of Purpura fulminans secondary to Morganella morganii bacteremia.
• To emphasize the importance of early diagnosis and management in this potentially fatal condition.
• To discuss the clinical presentation and treatment of PF in the context of a recent urinary tract infection intervention.

Main Methods:

• Case report detailing a patient with Purpura fulminans.
• Clinical presentation including purpuric lesions, fever, and hypotension.
• Management involved aggressive early resuscitation, intravenous antibiotics, and wound care.

Main Results:

• The patient presented with Purpura fulminans despite normal coagulation parameters and no evidence of disseminated intravascular coagulation.
• Morganella morganii was identified as the causative agent of bacteremia.
• The patient showed a favorable response to prompt medical intervention.

Conclusions:

• Purpura fulminans can be a cutaneous manifestation of Morganella morganii bacteremia.
• Early identification and tailored management, including antibiotics and resuscitation, are vital for improving outcomes.
• This case underscores the need to consider diverse pathogens in the etiology of Purpura fulminans.
