A cute febrile neutrophilic dermatosis (Sweet syndrome) is a reactive disorder characterized by painful, erythematous, cutaneous plaques and nodules, the onset of which is accompanied by fever, leukocytosis, and neutrophilia. In this multicenter study, Requena et al describe a series of 41 patients with Sweet syndrome in whom histopathologic analysis revealed an inflammatory infiltrate composed mainly of histiocytoid mononuclear cells that were revealed to be immature myeloid cells. The lesions showed a benign biological behavior and responded promptly to low doses of corticosteroids or nonsteroidal anti-inflammatory drugs.
