• Cutaneous vasculitis is not a specific disease, it mostly develops as secondary vasculitis due to an underlying disease (infection, malignancy, etc.) or drug. Idiopathic cases are less common.
• It is the most common type of vasculitis in clinical practice.
• In general, skin involvement is observed, systemic organ involvement is not expected.
• As a result of extravasation of erythrocytes from the affected vessel, palpable purpura is seen.
(Purpura, which develops in primary hemostasis disorders, is not palpable.)
The disease is usually mild and self-limited.
• Definitive diagnosis is made by demonstrating leukocytoclastic vasculitis in skin biopsy.
• In secondary cases, the underlying condition (disease, medication, etc.) is corrected. Steroids are used in idiopathic cases.
