[Bullous Sweet's syndrome with pulmonary involvement]

Acute febrile neutrophilic dermatosis (Sweet's syndrome) is a rare dermatosis characterized by painful papules and plaques accompanied by cutaneous infiltration with neutrophilic granulocytes. Bullous changes are observed in some cases. We report about a patient with osteomyelofibrosis who developed fever accompanied by painful plaques and confluent papules on both arms and thighs. The course of the disease was complicated by blistering and pulmonary infiltrates. After the diagnosis of bullous Sweet's syndrome was established, systemic therapy with glucocorticoids was successful in treating skin lesions and dyspnea.
