Background: İmmun deposits (especially IgG, IgM, IgA and Compleman C3) can be observed under direct immunofluorescence microscopy (DIF) in many patients with cutaneous small vessel vasculitis (CSV). There are some studies reporting various positivity rates in the literature. İn this study, we aimed to present the results of DIF microscopy of CSV cases in our ınstitute. Materyal and Methods: A total of 121 patients with CSV were included retrospectively in this study. All the cases have skin biopsy for DIF and histopathological examination and clinical data. A total of 6 groups were formed considering the clinical data of the cases and the Chapel Hill Consensus Conference vasculitis classification. The accumulation of at least one of the immun deposits (IgG, IgM, IgA ve C3) in basal membrane or perivascular (PV) field was assessed as ‘DIF positive’. The relationship between the presence of eosinophil and leucocytoclasia and the accumulation of immun deposits was investigated statistically. Results: DIF was positive in 58.7% (n:71/121) cases. DIF was positive in 50.9% (n: 28/55) of leukocytoclastic vasculitis cases, 67.4% (n: 31/46) of nonspecific CV cases, 44.4% (n: 4/9) of urticarial vasculitis cases and 75% of livedoid vasculitis cases (n: 3/4), 100% (n: 5/5) of henoch schonlein purpura (HSP) cases. There was not any accumulation in vasculopathy cases (n:2). There was not any relationship statistically between the presence of eosinophil and leucocytoclasia and the accumulation of immun deposits. The highest immun accumulation was C3 and the rate of IgA accumulation in HSP was 100%. Conclusion: In CSVs, high DIF positivity rates (especially C3) were determined. The determination of IgA deposits with DIF is very important for diagnosis of HSP. Performing of DIF in addition to clinical and histopathologic examination may be useful in CSVs.
