Mycoplasma Pneumoniae-Induced Mucositis Without Rash In An 11-Year-Old Boy

Key Clinical MessageMycoplasma pneumoniae is a frequent cause of childhood pneumonia, and extrapulmonary manifestations may be noted at the time of infection. While M. pneumoniae has long been associated with Stevens-Johnson syndrome, a separate diagnostic entity, Mycoplasma pneumoniae-induced rash and mucositis (MIRM), has recently been proposed to better characterize the rash and severe mucositis that some patients exhibit. A subset of patients with MIRM will have mucositis without skin rash. Physicians should recognize this clinical entity and be familiar with treatment options for MIRM.
