Nailfold Capillaroscopic (NFC) Changes in Vasculitis and Their Correlation with Systemic Involvement: A Cross-Sectional Study.

Background: Cutaneous vasculitis involves active inflammation of blood vessels of all caliber, leading to widespread systemic involvement and morbidity. The data regarding the utility of nailfold capillaroscopy (NFC) in cutaneous vasculitis is sparse. Since NFC offers direct visualization of the affected system, the microvasculature, its role appears promising and can serve as a valuable diagnostic adjunct.
