Stevens-Johnson syndrome due to Mycoplasma pneumoniae in an adult.

A case of Stevens-Johnson Syndrome (erythema multiforme major) due to Mycoplasma pneumoniae infection in a 45-year-old man is presented. This association has been previously reported only in children and young adults. A brief review of erythema multiforme, including the Stevens-Johnson syndrome, is described. M. pneumoniae should be added to the list of causes of the Stevens-Johnson syndrome in adults with pneumonia.
