Retiform Purpura - DermNet Retiform purpura is a cutaneous sign that falls within the spectrum of reticulate eruptions of vascular origin It comprises non-blanching, purpuric patches or plaques that are angulated or branching (reticular), often accompanied by skin necrosis and ulceration Retiform purpura occurs when cutaneous blood vessels are compromised, resulting in downstream skin ischaemia
Cutaneous small vessel vasculitis - DermNet In the skin, small vessel vasculitis presents with palpable purpura Cutaneous small-vessel vasculitis can be idiopathic primary, or secondary to infection, drug or disease It may be neutrophilic, lymphocytic or granulomatous on histopathology Small vessel vasculitis is also called immune complex small vessel vasculitis
