Sweet Syndrome in Infancy

Abstract

Sweet syndrome, or acute febrile neutrophilic dermatosis, is characterized by the presence of fever, peripheral leukocytosis, painful erythematous plaques and nodules, and a predominately neutrophilic dermal infiltrate. We report a case occurring in a 10-week-old male child, with preceding upper respiratory tract, and gastrointestinal infection symptoms. Sweet syndrome occurring in an infant should prompt a work-up for immunodeficiency, as well as a review of the peripheral blood smear to rule out the rare case of malignancy.
