title: Mycoplasma pneumoniae: an aetiological agent of acute haemorrhagic oedema of infancy.
abstract: Acute haemorrhagic oedema of infancy (AHEI) is considered a separate clinical entity among cutaneous small vessel vasculitis of childhood. It usually occurs in children younger than 2 years of age, with spontaneous recovery occurring within a few weeks. A history of recent upper respiratory or urinary tract infections or immunisation is found in most patients. Although Mycoplasma pneumoniae has been linked to a wide array of skin eruptions or diseases, it is not recognised as a possible cause of acute haemorrhagic oedema of infancy. The authors report a child with AHEI and a concurrent M. pneumoniae infection.
