AIMS: To document the association between erythema multiforme and Mycoplasma pneumoniae.

METHOD: All cases of erythema multiforme presenting to the dermatology department of Waikato Hospital over the summer of 1992/3 were tested for mycoplasma serology. Trends in recorded cases of M pneumoniae infection were examined from data supplied by the virology department of Waikato Hospital.

RESULTS

Four of seven cases of erythema multiforme were due to M pneumoniae infection. This was associated with a marked local increase in the number of M pneumoniae infections recorded in our hospital.

CONCLUSION

Mycoplasma serology is an important investigation in the management of erythema multiforme, especially when associated with an outbreak of M pneumoniae infections.
