Sweet's syndrome (SS) has been reported as an association with malignant neoplasms and autoimmune diseases, e.g., Behcet's disease, Sjogren's syndrome, and rheumatoid arthritis. But dermatomyositis (DM), one of the rare autoimmune diseases, was not reported as an associated disease of SS. We describe an interesting case of SS associated with DM. Diagnosis was made by skin biopsy, and subsequent clinical resolution occurred after institution of prednisolone.

Sweet's syndrome (SS), also known as acute febrile neutrophilic dermatosis, is characterized by the sudden onset of painful erythematous skin lesions together with fever and neutrophilia. SS can be associated with several disorders, such as malignancy, autoimmune disease, and infections. However, SS associated with liver cirrhosis is uncommon. We report a case of SS in a patient who was diagnosed with liver cirrhosis caused by chronic hepatitis B.
