Annular Neutrophilic Dermatoses

Neutrophilic dermatoses (NDs) are a group of diseases characterized by sterile neutrophilic infiltrations. Many of the NDs usually present with infiltrated erythematous plaques, nodules, urticarial plaques, or pustules. Lesions may show variability, and atypical presentations may develop among the NDs. Annular lesions have been reported in many NDs and may lead to diagnostic problems. Clinical features and histopathologic findings such as localization of the neutrophilic infiltrate, existence of other cell types, and absence of true vasculitis may be helpful to distinguish NDs.
