ABSTRACT
Mycoplasma pneumoniae (M. pneumoniae) is one of the most common causes of respiratory tract infections in pediatric and adult populations worldwide. M. pneumoniae is also associated with extrapulmonary complications, such as mucocutaneous eruptions. In dermatologic disorders, M. pneumoniae infection is known to be associated with erythema multiforme and Stevens-Johnson syndrome in children and young adults. Recently, several cases with M. pneumoniae-associated mucositis, which lacks typical target lesions, have been reported. The term Mycoplasma-induced rash and mucositis was suggested as a revised version of the term, Mycoplasma pneumoniae-associated mucocutaneous disease, which previously included erythema multiforme and Stevens-Johnsons syndrome. This revision helps to distinguish Mycoplasma-induced rash and mucositis, which has a distinct morphology, mild disease course, and potentially important clinical implications regarding treatment. Herein, we report a patient with Mycoplasma-induced rash and mucositis.
