[Idiopathic pustular and bullous variants of Sweet syndrome].

We report on the case of a 62-year-old patient with disseminated pustular plaques affecting especially his face and hands. These lesions exhibited severe blistering later in the course. The diagnosis of an unusual variant of an acute febrile neutrophilic dermatosis (Sweet's syndrome) was histologically confirmed. Pustular lesions are known to occur in Sweet's syndrome. Secondary development into bullous lesions, however, has not previously been described. No associated disease has so far been detected.
