A retrospective survey during a 2-year period disclosed 18 patients with acute febrile neutrophilic dermatosis (Sweet´s syndrome). An associated lympho- or myeloproliferative malignancy was found in 6 patients. Attacks of Sweet´s syndrome preceded the diagnosis of neoplasia in 4 patients (3 months to 6 years). Some differences in symptoms and signs were found in the group of patients with associated malignancy compared with the group without, that is, male predominance, mucosal symptoms, anemia, and frequent recurrence of skin symptoms. The onset of Sweet´s syndrome indicates an acute infectious disease, and the patients are frequently referred to departments of internal medicine and infectious diseases. In addition, the skin lesions may mimic those which often accompany a generalized infection (erythema multiforme, erythema nodosum, vasculitis, pustular eruptions and urticaria). Since Sweet´s syndrome may precede the possibly associated malignant disease, the initial diagnosis of the syndrome is important and should be made with confidence with increasing awareness of the characteristic symptoms.
