We describe the case of a 15-month-old boy with Kawasaki disease who developed varicella 7 days after the beginning of the disease and diffuse plaque psoriasis after 43 days. Associations between Kawasaki disease and psoriasis, between Kawasaki disease and varicella and between varicella and psoriasis have all been reported in the literature. The triple association of Kawasaki disease, varicella and psoriasis is very rare. Neither the double nor the triple associations are well known among a diverse group of practitioners.
