Recurrent reactive infectious mucocutaneous eruption (RIME): Insights from a child with three episodes

Abstract Reactive infectious mucocutaneous eruption (RIME) was recently proposed to replace the term Mycoplasma pneumoniae (MP)‐induced rash and mucositis to account for the fact that non‐MP pathogens may also cause rash and mucositis. In this report, we describe a unique case of recurrent RIME featuring a total of three episodes. As two of the episodes demonstrated contemporaneous infection with MP and group A streptococcus or influenza B, this case lends further support to use of the term RIME. In addition, although RIME typically involves at least two mucous membranes, this case shows that recurrent episodes may fall into the rare exception in which mucositis is limited to one site.
