Mycoplasma pneumoniae-induced recurrent Stevens-Johnson syndrome in children: a case report.

Mycoplasma pneumoniae, the major pathogen of primary atypical pneumonia, is reported as the most common infectious agent associated with Stevens-Johnson syndrome (SJS) in children. For that reason it is important to consider mycoplasma infection also in the absence of classical pulmonary symptoms. SJS is a rare and acute, self-limited disease, characterized by severe inflammation and necrosis of two or more mucous membranes. We report the case of a 12-year-old boy with a diagnosis of SJS induced by M. pneumoniae infection. The patient's SJS relapsed 8 months after discharge. When the condition is recurrent, it is important early on to identify the cause of a single episode to optimize care and therapeutic choices.
