AbstractNeutrophilic dermatoses are inflammatory disorders where normal neutrophils infiltrate the skin without infection. Sweet's syndrome, pyoderma gangrenosum, subcorneal pustulosis, erythema elevatum diutinum and a few other conditions are included in the spectrum of neutrophilic dermatoses. In addition to their typical presentation, atypical and overlap forms of these disorders may be observed. According to the location of the neutrophilic infiltrate, three clinical forms are distinguished: superficial (epidermal), en plaques (dermal) and deep (dermal and hypodermal). During the disease course, other tissues can be affected by the same neutrophilic infiltrate. An association with other systemic diseases including malignant blood disorders, inflammatory bowel diseases and autoimmune disorders is frequent. The mechanisms leading to the invasion of the skin by neutrophils remains not completely elucidated. Treatment depends on the intensity and the acute or chronic form of the disease. In acute and severe forms, systemic corticosteroids are first-line therapy, whereas colchicine, dapsone, and even topical corticosteroids could be used in milder presentations of the disease.Copyright © 2010 Société nationale française de médecine interne (SNFMI).
