Final answer:
The skin manifestations of ANCA associated vasculitis include palpable purpura, ulcers, nodules, purpura, livedo reticularis, and skin lesions like rash and urticaria.
Step-by-step explanation:
The skin manifestations of ANCA associated vasculitis can vary depending on the type of vasculitis. ANCA associated vasculitis includes three main types: granulomatosis with polyangiitis (formerly known as Wegener's granulomatosis), microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis (formerly known as Churg-Strauss syndrome). In granulomatosis with polyangiitis, skin manifestations can include palpable purpura (small purple spots), ulcers, and skin nodules. In microscopic polyangiitis, skin manifestations may include purpura, livedo reticularis (net-like pattern on the skin), and skin ulcers. Eosinophilic granulomatosis with polyangiitis typically presents with skin lesions such as rash, urticaria (hives), and nodules.
