Final answer:
The extracutaneous manifestations of small vessel vasculitis include hypopigmented skin, skin lesions, and nodules, loss of peripheral nerve function, and loss of fingers, toes, and extremities. Additionally, symptoms such as nausea, vomiting, photophobia, stiff neck, and confusion can occur if the central nervous system is affected.
Step-by-step explanation:
Extracutaneous manifestations of small vessel vasculitis include:
Hypopigmented skin, skin lesions, and nodules: Small vessel vasculitis can cause changes in the skin, leading to hypopigmented areas, skin lesions, and nodules.
Loss of peripheral nerve function: In some cases, small vessel vasculitis can affect the peripheral nerves, leading to loss of sensation or function in the affected areas.
Loss of fingers, toes, and extremities: Severe cases of small vessel vasculitis that go untreated or are inadequately treated can result in tissue damage and necrosis, leading to the loss of fingers, toes, and sometimes even larger extremities.
Nausea, vomiting, photophobia, stiff neck, confusion: These symptoms can arise if small vessel vasculitis affects the central nervous system, leading to inflammation and damage.
