[Acute febrile neutrophilic dermatosis (Sweet's syndrome) in a patient with agnogenic myeloid metaplasia]

Abstract

A 60-year-old man with a one-year history of agnogenic myeloid metaplasia was admitted to the hospital because of fever and a skin eruption. He had fever, anemia, hepatosplenomegaly, and a raised painful erythematous plaque in the face. The same kind of skin lesion developed thereafter at a venipuncture site in the left forearm. Bacterial cultures were negative. There was no response to antibiotic treatment. A biopsy specimen of the skin lesion revealed a dense dermal infiltration with mature neutrophils. A diagnosis of Sweet's syndrome was made. Fever and skin eruptions responded rapidly to prednisolone (PSL). Although the disease frequently recurred on rapid tapering of PSL, skin lesions cleared without scarring on a prolonged course of PSL. Four months after withdrawal of PSL, Sweet's syndrome recurred. A high dose PSL was given without benefit. He died of disseminated candidiasis.
