title: Mycoplasma pneumonia--associated mucocutaneous disease in children: dilemmas in classification.
abstract: There is controversy regarding precise definitions for Stevens-Johnson syndrome (SJS) and erythema multiforme (EM) major because of overlap in clinical presentations. SJS and EM major associated with Mycoplasma pneumoniae have been reported to occur in children, but Mycoplasma is more commonly reported with SJS. We sought to further characterize Mycoplasma-associated mucocutaneous disease. Through retrospective chart review over 10 years, six children hospitalized with a diagnosis of SJS who also tested positive for Mycoplasma infection were reviewed. Using documented physical examinations and photographs, diagnoses of SJS or EM major were retrospectively made based upon cutaneous lesional morphology employing the classification system proposed by Bastuji-Garin et al. The majority of patients were boys, with limited acral cutaneous lesions. All patients required prolonged hospitalization because of mucosal involvement and had good short-term outcomes. When the classification system was retrospectively applied, five of the six patients were reclassified with a diagnosis of EM major instead of SJS. Children with Mycoplasma-associated EM major and SJS in our small retrospective series appeared to have significant mucosal involvement but more limited cutaneous involvement with lesional morphology, which is more characteristic of EM major.
