A severe case of reactive infectious mucocutaneous eruption associated with two possible triggers: Coronavirus and group A streptococcus

Reactive infectious mucocutaneous eruption (RIME) is a newly defined condition characterized by mucocutaneous blistering secondary to upper respiratory infections and encompasses Mycoplasma pneumoniae‐induced rash and mucositis, broadening the disease spectrum to include various infectious etiologies. We present a severe RIME case involving a 5‐year‐old female with concurrent coronavirus NL63 and group A streptococcus infections. Diagnosis complexity stemmed from overlapping clinical features with other severe mucocutaneous eruptions such as Stevens‐Johnson syndrome/toxic epidermal necrolysis/drug‐induced necrolysis. This case underscores the need for comprehensive infectious workup and emphasizes the clinical diagnostic spectrum of drug‐induced and infection‐induced desquamative skin and mucosal disease.
