The nomenclature of cutaneous small vessel vasculitis (CSVV) is diverse and often confusing. The American College of Rheumatology established a list of criteria for the classification of hypersensitivity vasculitis (leukocytoclastic vasculitis). Its pathophysiology includes immune complex deposition and a wide range of skin lesions. Leukocytoclastic vasculitis (LCV), also termed hypersensitivity vasculitis, is a small-vessel vasculitis with a reported incidence rate of about 30 cases per million people per year and is thought to affect men and women in equal numbers.1,2 The skin is the organ most commonly involved in LCV.

Cutaneous leukocytoclastic vasculitis (CLCV) is characterized by the inflammation of superficial small vessels of the skin that clinically presents as a palpable purpura.1,2 Type III hypersensitivity, wherein immune complexes play a significant role, is considered a key mechanism underlying CLCV pathophysiology.1 Numerous factors promote CLCV, although infection and drugs are etiologically . Leukocytoclastic vasculitis (LCV) refers to small blood vessel inflammation.
