[Sweet's syndrome].

Sweet's syndrome or acute febrile neutrophilic dermatosis is relatively frequent. It can be isolated or associated to other diseases, particularly, inflammatory or autoimmune diseases, lymphoproliferative or malignant disorders. In this retrospective study, we report 10 cases of Sweet's syndrome recorded over a 42 months period. The female predominance was net (9 womens for 1 man). The mean age was 45 years. The diagnosis was established, in all cases, on clinical, biological and histological criteria. The lesions occurred most commonly on legs (9 cases). The failure of antibiotics has been noted in all patients, and colchicine has been demonstrated efficient in 6 patients. Our study confirms the interest of cutaneous biopsy in case of papulo-nodular lesions which has not respond to antibiotics.
