title: Case of granulocyte colony-stimulating factor-induced Sweet's syndrome.
abstract: A 33-year-old male was referred with a two-week history of fevers to 40 degrees C and painful, erythematous skin and oral mucosal eruptions that had failed to respond to multiple anti-infectious agents. He had a recent diagnosis of a "myeloproliferative disorder with myelodysplastic features" on bone marrow biopsy, with associated pancytopenia. Two weeks before admission, he had been treated with a course of granulocyte colony-stimulating factor (G-CSF) at a dose of 300 microg/day in an attempt to improve his neutropenia. After four days of treatment, the fever and lesions developed. Infectious evaluation was negative; however, biopsies of the skin and oral mucosal lesions revealed histology consistent with Sweet's syndrome. Intravenous methylprednisolone (30 mg/day) was started with prompt defervescence and resolution of the lesions within days. With the increasing use of G-CSF, Sweet's syndrome is becoming more commonly recognized as an adverse effect. This is the first case of G-CSF-induced Sweet's syndrome to demonstrate gingival involvement.
