摘要

Sweet's syndrome (SS) or acute febrile neutrophilic dermatosis is a reactive process that presents in different clinical settings and ranges from classical (idiopathic), malignancy associated or drug induced. The authors describe a 51-year-old Caucasian woman referred to our department with a 3-day history of pseudovesicular reddish papules on her neck, upper trunk and limbs. Two days prior to the eruption, aceclofenac 100 mg every 8 h was initiated for lower back pain. She also complained of high fever (39°C), arthralgias and general malaise. Laboratory evaluation showed an elevation of erythrocyte sedimentation rate and C reactive protein. A biopsy specimen of skin lesions showed throughout the upper reticular dermis a dense infiltrate of mature neutrophils. Aceclofenac was discontinued and oral prednisolone (0.5 mg/kg) was started. Fever resolved within 48 h, whereas cutaneous lesions cleared within the first week. No relapse was noted after a 6-month follow-up period. Drug-induced SS by aceclofenac diagnosis was sustained by the presence of all the five diagnostic criteria for drug-induced SS presented by Walker and Cohen in 1996. Several hundred cases of SS have been reported in the literature. However, drug-induced SS represent overall less than 5% of all cases, mostly as isolated clinical cases. Reports of nonsteroidal anti-inflammatory drug-induced SS include diclofenac, celecoxib and rofecoxib. Our patient represents the first case of aceclofenac-induced SS and illustrates the need to enquire about recent drugs in a patient with suspicion of SS.
