Acute febrile neutrophilic dermatosis also known as Sweet’s syndrome is an uncommon condition named after the English dermatologist, Dr Robert Sweet, who first described it in 1964. Sweet’s syndrome usually presents with fever, a rise in white blood cells, raised red skin rashes and neutrophils (pus cells) infiltrating the upper layer of the skin.
Fever and a rise in white blood cells are not always present. Sweet’s syndrome is sometimes initially mistaken for an infection or medication allergy.
