Acute Febrile Neutrophilic Dermatosis
Key Points
Acute febrile neutrophilic dermatosis can occur in patients who have certain disorders (classical form) or take certain drugs (drug-induced form), but about 25% of patients have an underlying cancer (cancer-associated form), usually a hematologic cancer. Diagnose acute febrile neutrophilic dermatosis based on the appearance of the lesions and presence of an associated disorder or drug, and confirm with biopsy when necessary. Treat most patients with systemic corticosteroids or, alternatively,colchicineorpotassium iodide.
