Answers based on clinicopathologic correlation
Despite review of numerous articles about LV, we could not find compelling answers to the following questions:
How can the varied appearance clinically of lesions be explained, they ranging from macules to papules, plaques, blisters, nodules, ulcers, and scars?
Is LV associated with livedo reticularis or livedo racemosa or not?
What is the type and the site of vessels affected with fibrin deposits and thrombi in LV?
What is the composition and the amount of infiltrate accompanying?
Why are lesions of LV so painful?
Is LV a disease of the legs or a systemic process?
Why are results of investigations by direct immunofluorescence contradictory?
