Acute febrile neutrophilic dermatosis (Sweet's syndrome) in hairy cell leukemia: a case report.
Sweet's syndrome is a cutaneous reactive process that is usually associated with fever, but rarely occurs in patients with hairy cell leukemia (HCL). We report the case of a patient with HCL who developed typical Sweet's syndrome five months after the diagnosis of HCL. Skin eruptions and constitutional symptoms subsided rapidly after short-term systemic adrenocorticosteroid treatment without recurrence, until the patient died from disease exacerbation and uncontrolled infection. According to his manifestations, chemical allergens, microorganisms or HCL progression were unlikely to have been the precipitating factors for development of Sweet's syndrome. Because immunologic disorders and opportunistic infection are not uncommon in patients with HCL, a skin biopsy should be taken as early as possible when cutaneous lesions and fever develop in order to establish a correct diagnosis. Hence, unnecessary and prolonged use of antibiotics is avoided and prompt relief of the symptoms by appropriate management can be achieved.
