[Sweet's syndrome. Presentation of six cases and review of the literature].

The acute febrile neutrophilic dermatosis or Sweet syndrome, initially described in 1964 by Robert Sweet (1). It is characterized fever, neutrophilic leucocytosis, abrupt appearance of erythematous, painful, cutaneous plaquets and dense dermal infiltrate consisting of mature neutrophils without vasculitis sings. Malignancy has been described in the 10-15% of the reported cases. We report our series of 6 patients diagnosticated of this illness in our department. One of this patients has Sweet syndrome associated with a malignancy disorder. All of them had diagnostic criteria of the described disease and had good response to corticotherapy. We also report a bibliographic review of this infrequent syndrome.
