This descriptive study aimed to evaluate the frequency and the types of mucocutaneous manifestations associated with multisystem inflammatory syndrome in children (MIS-C). A cohort of 49 patients was reviewed. There were 6 patients (12.2%) whose mucocutaneous findings were observed by the clinicians on admission, whereas 26 (53%) patients had at least one of the histories of rash or desquamation associated with fever before the admission. Exanthems in our experience demonstrated a variety of morphologies, including morbilliform, urticarial, petechial, and maculopapular forms. Mucosal involvement (conjunctivitis and strawberry tongue) was observed only in 2/6 (34%) patients. In the coronavirus disease 2019 pandemic era, while evaluating the criteria for MIS-C, the history of previous cutaneous findings given by parents/caregivers is also important. There was no pathognomonic rash for MIS-C and a variety of cutaneous findings with a short lifespan can be associated with MIS-C.

儿童多系统炎症综合征的皮肤黏膜发现：单中心经验

这项描述性研究旨在评估与儿童多系统炎症综合征 (MIS-C) 相关的皮肤黏膜表现的频率和类型。回顾了 49 名患者的队列。入院时有 6 名患者 (12.2%) 的皮肤黏膜表现被临床医生观察到，而 26 名 (53%) 患者入院前至少有一种与发热相关的皮疹或脱屑病史。根据我们的经验，出疹表现出多种形态，包括麻疹、荨麻疹、瘀点和斑丘疹形式。仅在 2/6 (34%) 患者中观察到粘膜受累（结膜炎和草莓舌）。在 2019 年冠状病毒病大流行时代，在评估 MIS-C 标准的同时，父母/看护人提供的先前皮肤检查结果的历史也很重要。
