Localized sweet's syndrome in an irradiated field

Abstract

Sweet's syndrome is a reactive dermatosis characterized clinically by fever, leukocytosis, and multiple, erythematous, painful plaques. Histopathologic examination reveals a band-like dense dermal inflammatory infiltrate composed mainly of neutrophils with papillary dermal edema, and no features of vasculitis. We report a case of a 56-year-old female diagnosed with cervical cancer, who underwent surgery and concurrent chemoradiation therapy. Approximately 3 years after completing treatment, she presented with erythematous plaques, principally within the radiation field; the skin biopsy showed features consistent with Sweet's syndrome.
