Sweet syndrome (SS), also called acute febrile neutrophilic dermatosis, is rare in the pediatric population, especially in infants and neonates. We present a case of infantile SS that developed 1 day after the MMRV vaccine; we suggest a possible causal relationship between the MMRV vaccine and SS.
Keywords: MMRV vaccine; Sweet syndrome; acute febrile neutrophilic dermatosis; hypersensitivity reaction; vaccine-induced skin reaction.
