© 2022 Sociedade Brasileira de DermatologiaObjectives: multi-system ınflammatory syndrome in children (MIS-C) is an immune-mediated process that develops after infections like SARS-CoV-2. The authors aimed to reveal the mucocutaneous findings of patients diagnosed with MIS-C at presentation and evaluate the frequency of these mucocutaneous findings and their possible relationship with the severity of the disease. Methods: A prospective study was conducted of 43 children admitted to a tertiary hospitals between January 2021 and January 2022 who met Centers for Disease Control and Prevention criteria for MIS-C. Results: 43 children (25 [58.1%] male); median age, 7.5 years [range 0.5‒15 years]) met the criteria for MIS-C. The most common symptom was cutaneous rash 81.4%, followed by gastrointestinal symptoms 67.4%, oral mucosal changes 65.1%, and conjunctival hyperemia 58.1%. The most common mucosal finding was fissured lips at 27.9%, diffuse hyperemia of the oral mucosa at 18.6%, and strawberry tongue at 13.9%. Urticaria (48.8%) was the most common type of cutaneous rash in the present study's patients. The most common rash initiation sites were the trunk (32.6%) and the palmoplantar region (20.9%). The presence or absence of mucocutaneous findings was not significantly associated with disease severity. Study limitations: The number of patients in the this study was small. Conclusions: The present study's prospective analysis detected mucocutaneous symptoms in almost 9 out of 10 patients in children diagnosed with MIS-C. Due to the prospective character of the present research, the authors think that the characteristic features of cutaneous and mucosal lesions the authors obtained will contribute to the literature on the diagnosis and prognosis of MIS-C.
