Érythème périnéal récidivant toxinique chez un enfant de 11 ans

Recurrent toxin-mediated perineal erythema is a cutaneous disease mediated by superantigens which are toxins produced by staphylococci and streptococci. It is characterized by recurrent macular erythema involving the perineum. Streptococcus pyogenes is the most common cause of recurrent toxin-mediated perineal erythema, with Staphylococcus aureus being isolated most rarely. This observation emphasizes the possibility of atypical clinical presentation with pustular lesions, and dermatologists must be mindful of this aetiology in order to isolate bacterial toxins and to initiate appropriate antibiotics.
