Sweet's syndrome is acute febrile neutrophilic dermatosis. It frequently involves upper and lower limbs, head and neck. The dermatologic symptom of Sweet's syndrome is elevated plaque, pain, and skin erythema. We have experienced a case of Sweet's syndrome which involved auricle and have needed to differentiate it from perichondritis. For the cases of assumed perichondritis that do not improve symptoms with treatment compatible for perichondiritis, Sweet's syndrome could be the etiology.
