Cutaneous Small Vessel Vasculitis: A Practical Guide to Diagnosis and Management

Area of Science:

• Dermatology
• Rheumatology
• Immunology

Background:

• Cutaneous vasculitis presents diagnostic challenges, appearing as a skin manifestation of systemic vasculitis, a skin-limited variant, or isolated skin vasculitis.
• Distinguishing between these forms and identifying underlying conditions is crucial for appropriate patient management.
• Current treatment for cutaneous small vessel vasculitis (CSVV) relies heavily on case reports and expert consensus, utilizing immunomodulatory and immunosuppressive therapies.

Purpose of the Study:

• To present a systematic and stepwise approach for evaluating patients with cutaneous vasculitis.
• To provide evidence-based guidance on managing cutaneous small vessel vasculitis (CSVV).
• To differentiate between skin-limited and systemic vasculitis.

Main Methods:

• Systematic review of studies on classification, evaluation, and management of skin vasculitis.
• Evidence-based approach to diagnosis and treatment of cutaneous vasculitis.
• Stepwise evaluation protocol for patients presenting with skin vasculitis.

Main Results:

• A structured diagnostic pathway is essential for accurate classification of cutaneous vasculitis.
• Management strategies for CSVV involve a range of immunomodulatory and immunosuppressive treatments.
• Ongoing research aims to further refine classification, evaluation, and management protocols.

Conclusions:

• A systematic evaluation is necessary to correctly diagnose and manage cutaneous vasculitis, including differentiating skin-limited from systemic disease.
• Evidence-based guidelines are presented for the management of cutaneous small vessel vasculitis (CSVV).
• Further research is needed to advance the understanding and treatment of skin vasculitis.
