Definition

Sweet syndrome — also known as acute febrile neutrophilic dermatosis — is a skin condition marked by fever and painful skin lesions that appear mainly on your face, neck, back and arms. Although middle-aged women are most likely to develop Sweet syndrome, the condition can also affect men, older adults and even infants.

The exact cause of Sweet syndrome often isn't known. In some people, it's triggered by an infection, illness or certain medications. Sweet syndrome can also occur with some types of cancer and other serious health problems.

Most often, Sweet syndrome isn't serious and will clear on its own in a few months. Healing is much more rapid with treatment.
