Extrapulmonary manifestations of Mycoplasma pneumoniae infection in children

Mycoplasma pneumoniae ( M. pn. ), which is a well-known pathogen to cause atypical pneumonia, in 25% of cases can lead to a wide range of extra-pulmonary symptoms, reflecting damage to almost any organ or organ system (skin and mucous membranes, nervous, cardiovascular, gastrointestinal, urinary system etc.). Aspecific syndrome Mycoplasma pneumoniae -induced rash and mucositis (MIRM) has been identified recently. Among the CNS manifestations associated with M. pn. , acute postinfectious cerebellar ataxia is worth mentioning. In this article we present clinical cases of a 14-year-old boy and a 6-year-old girl with extrapulmonary manifestations of M. pn. infection. This article considers etiological, pathogenetic and clinical features of mycoplasma infection in children with an emphasis on extra-respiratory manifestations.
