Sweet's syndrome is a dermal neutrophilic inflammatory dermatosis characterized by unrestricted neutrophil production with consequent infiltration of the skin and in some cases other organs. We report a 4 month old baby boy with multiple well-defined skin coloured to erythematous, edematous papules and plaques studded with sterile pustules along the periphery involving the entire body since 1 week with sparing of palms, soles and mucosae. Thick crusts were seen involving the entire scalp. Laboratory investigations and histopathology were suggestive of neutrophilic dermatoses (Sweet's syndrome).
