M. pneumoniae-induced rash and mucositis (MIRM), proposed as a unique entity apart from erythema multiforme (EM), Steven Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) by Canavan et al. in 2015, follows a less severe course and is associated with less morbidity and mortality.1,2 In SJS and TEN, widespread, confluent skin lesions, positive Nikolsky sign, and significant epidermal detachment are present.3 In MIRM, mucositis, especially oral, is nearly universal (94%) and predominant over a less marked or absent cutaneous involvement.1,4 It is a major cause of morbidity, may lead to multiple confluent erosions, hemorrhagic crusting, and sparse vesiculobullous perilabial eruptions, and, rarely, to sequelae such as mucosal synechiae and pigmentary changes.
