A Case of the Sweet's Syndrome Associated with Anti tuberculous Medication

Clinical manifestations of Sweet’s syndrome typically include fever, leukocytosis, and tender, erythematous plaques with a dermal infiltration of mature neutrophils. Sweet’s syndrome is divided into three clinical categories: idiopathic, malignancyassociated, and drug-induced. No correlation between antituberculous medication and Sweet’s syndrome has previously been reported. Here, we describe a 79-year-old woman who developed an acute onset of fever and skin eruption after taking antituberculous medication. The clinical pattern and the result of skin biopsy were consistent with Sweet’s syndrome. After cessation of rifampin, the fever and skin rash disappeared. Thus, we diagnosed the patient with Sweet’s syndrome, caused by rifampin. To our knowledge, this is the first reported case of rifampin-induced Sweet’s syndrome. (Korean J Med 2011;80:S188-S193)
