Purpose of review: Neutrophilic dermatoses are defined by the presence of a sterile neutrophilic infiltrate on histopathology. This review focuses on the pathogenesis, epidemiology, clinicopathological features, diagnosis, and management of four disorders: Sweet syndrome, pyoderma gangrenosum, Behçet syndrome, and neutrophilic eccrine hidradenitis.
Recent findings: Recent studies have provided insight into the complex pathogenesis of neutrophilic dermatoses. Evidence supports an intricate interplay of abnormal neutrophil function and inflammasome activation, malignant transformation into dermal infiltrating neutrophils, and genetic predisposition.
Summary: Neutrophilic dermatoses have diverse cutaneous and extracutaneous manifestations and may be associated with significant morbidity and mortality. Common underlying associations include infectious, inflammatory, and neoplastic disorders, as well as drug reactions. Emerging diagnostic and therapeutic frameworks identify an expanding role for biologic and targeted anti-inflammatory therapies.
期刊介绍：
This journal intends to review the most significant recent developments in the field of dermatology. By providing clear, insightful, balanced contributions by expert international authors, the journal aims to serve all those involved in the diagnosis, treatment, management, and prevention of dermatologic conditions. We accomplish this aim by appointing international authorities to serve as Section Editors in key subject areas across the field, such as epidemiology, surgery, pharmacology, clinical trial design, and pediatrics. Section Editors select topics for which leading experts contribute comprehensive review articles that emphasize new developments and recently published papers of major importance, highlighted by annotated reference lists. We also provide commentaries from well-known figures in the field, and an Editorial Board of more than 20 internationally diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research.
