Final answer:

Cutaneous small vessel vasculitis (CSVV) is commonly caused by infections, drug hypersensitivity, and systemic autoimmune disorders. Conditions such as Lyme disease, systemic lupus erythematosus, and infections by various viruses can lead to CSVV. Treatment involves managing underlying causes and inflammation with medications.

Step-by-step explanation:

The most common causes of cutaneous small vessel vasculitis (CSVV) include a variety of underlying conditions and external factors. These can range from infections such as hepatitis or Lyme disease, which is characterized by a bull's-eye rash, to drug hypersensitivity reactions. Additionally, systemic diseases like systemic lupus erythematosus, rheumatoid arthritis, and other autoimmune disorders are known to be associated with CSVV. Infections that commonly affect the skin such as those caused by human papillomavirus, parvovirus B19, and herpes simplex virus, as well as staphylococcal scalded skin syndrome caused by S. aureus, can also precipitate CSVV. Environmental factors, such as exposure to chemicals or medication, can lead to CSVV as well. Treatment for CSVV often involves addressing the underlying cause, if identified, along with medications like corticosteroids to reduce inflammation and manage symptoms.
