Mycoplasma pneumoniae-related erythema multiforme: clinical and histological features. A single center series of 33 cases compared to 100 cases induced by other causes

Clinical aspects of Mycoplasma pneumoniae-related erythema multiforme (MP-EM) have been poorly described, MP-EM has a distinctive presentation compared with non-MP EM with diffuse atypical targets, and severe and extensive mucositis. Histology is similar to toxic epidermal necrolysis. Mucosal involvement management is essential in MP-EM to prevent possible sequelae.
