Polycyclic urticarial plaques with purpuric on her anterior thighs. 

#Urticarial_vasculitis is a condition characterized by urticarial lesions lasting longer than 24 hours, often resolving with purpura or hyperpigmentation. It involves small vessel inflammation (leukocytoclastic vasculitis) and may present with systemic symptoms like fever, arthralgia, or malaise. Diagnosis is confirmed with a skin biopsy showing vessel inflammation and laboratory evaluation for autoimmune or infectious causes. Mild cases are treated with antihistamines, while severe or systemic forms may require corticosteroids or immunosuppressants.
