Cutaneous necrotizing vasculitis: a rational therapeutic approach

Area of Science:

• Dermatology
• Rheumatology
• Immunology

Background:

• Cutaneous necrotizing vasculitis (CNV) is a diverse group of disorders.
• Clinically, CNV is identified by palpable purpura.
• Histologically, it shows segmental inflammation and vessel wall necrosis.

Purpose of the Study:

• To outline the clinical and histological characteristics of CNV.
• To identify potential causes and triggers of CNV.
• To propose a rational therapeutic approach for CNV management.

Main Methods:

• Clinical presentation review.
• Histopathological analysis of affected vessels.
• Etiological investigation including drug, allergen, infection, and malignancy screening.

Main Results:

• CNV can manifest with skin lesions, but systemic involvement is possible.
• Up to 60% of CNV cases have unknown etiology.
• Identified causes include drugs, allergens, infections, systemic inflammatory disorders, and neoplasms.

Conclusions:

• Effective CNV management starts with identifying and removing underlying causes.
• Cessation of triggers often resolves cutaneous lesions and systemic symptoms.
• Refractory cases may require anti-inflammatory or immunosuppressive treatments.
