* Articles related to Kawasaki disease in adults mostly referred to cases with Kawasaki-like disease/symptoms and multisystem inflammatory syndrome. The database also contained a lot of pediatric cases that were excluded from our search. ** Our findings about eosinophilic granulomatosis with polyangiitis (EGPA), also revealed cases with SARS-CoV (+) infection mimicking EGPA. *** Cutaneous reactions in patients with SARS-CoV2 (+) infection counted > 400 cases, and they were excluded from this search.
