Fulminans Purpura due to Morganella morganii .

UNLABELLED: Purpura fulminans (PF) is a dermatological manifestation of a life-threatening condition characterized by disseminated intravascular coagulation and endovascular thrombosis. The idiopathic/infectious form is the most common and usually associated with infection by Neisseria meningitidis or Streptococcus pneumoniae . We describe a case of Morganella morganii -induced bacteriaemia complicated with PF in an individual who had undergone a recent urinary tract infection intervention. The patient presented with purpuric skin lesions, fever and hypotension but had no alterations in coagulation parameters or disseminated intravascular coagulation. Aggressive early resuscitation, intravenous antibiotics and wound care were essential to a favourable response.

LEARNING POINTS: Purpura fulminans is a dermatological manifestation of an underlying life-threatening condition, and is characterized by disseminated intravascular coagulation and skin necrosis.It is a morbid and potentially fatal condition that can be a cutaneous manifestation of Morganella morganii bacteraemia.Early identification and accurate diagnosis of the underlying cause can help minimize morbidity and mortality; management should be tailored to the individual, with the use of intravenous antibiotics, necrotic skin excision and aggressive early resuscitation.
