Mycoplasma pneumoniae infection is generally associated with respiratory symptoms. Abnormalities in almost every organ system have been described as examples of extrapulmonary manifestations.1 However, skin vasculitis is very rare: we found reports of only 2 cases of serologically confirmed M pneumoniae infection with cutaneous biopsy-proven vasculitis in the English-language literature.2,3 On the other hand, M pneumoniae causes central nervous system complications such as aseptic meningitis, meningoencephalitis, transverse myelitis, brainstem dysfunction, and Guillain-Barré syndrome, as well as many other symptoms.1,4 Three mechanisms for M pneumoniae–associated neurological disease have been postulated: immune-mediated damage, direct invasion of the central nervous system, and production of a neurotoxin by M pneumoniae.4 We report a case of cutaneous leukocytoclastic vasculitis and encephalitis associated with acute M pneumoniae infection. To our knowledge, this association has not been previously reported.
