© 2022 Australasian College of Dermatologists.Background: Little is known about mucocutaneous involvement in critically ill patients with the multisystem inflammatory syndrome in children (MIS-C). The aim of our study was to describe the localisation and variety of rash and to investigate whether presenting with rash at admission alters the clinical course of MIS-C. Methods: This prospective, observational cohort study was conducted amongst children under 18 years of age who were admitted to our paediatric intensive care unit (PICU) between May 2020 and May 2021 with a possible diagnosis of MIS-C. Results: A total of 33 children with MIS-C, 21 boys (64%), with a median age of 9.4 years (3.4–11.5) were enrolled. Twenty-four children presented with mucocutaneous symptoms (72%). Age, male gender, PICU length of stay, presenting symptoms, inotrope requirement, the existence of myocarditis or respiratory failure were higher but not significantly different in patients with rash compared to those without rash (P > 0.05). The median duration of symptoms before admission and presence of cervical lymphadenopathy were significantly higher in patients than those without rash (P < 0.05). Children with a rash had a significantly higher neutrophil count, CRP, procalcitonin, troponin levels and lower lymphocyte counts and albumin levels than those without rash (P < 0.05). Twelve children with rash (50%) had symmetrical intertriginous distribution. Two children had erythematous lesions on the areola and the surroundings. In conclusion, intertriginous involvement, periareolar erythema and other mucocutaneous manifestations might be the first alarming symptoms of moderate to severe MIS-C. Therefore, close monitoring with a multidisciplinary approach should be considered for these patients to assess potential disease progression.
