Extrapulmonary involvement associated with Mycoplasma pneumoniae infection

Mycoplasma pneumoniae infection usually presents with upper and lower respiratory tract infection. Extrapulmonary involvement is not uncommon, however. We report two cases of predominantly extrapulmonary manifestations of Mycoplasma pneumoniae infection without significant pulmonary involvement. Both cases were diagnosed by serology. These cases illustrate the diversity of clinical presentations of Mycoplasma pneumoniae infection. Clinicians should maintain a high index of suspicion.
