IL10 and histiocytic sarcoma: The results showed only fair diagnostic value of IL-10 in differentiating TLE + HS from TLE-HS (Area under curve (AUC) = 0.692, confidence interval (CI) = 0.57–0.80, p = 0.001), XLE (AUC = 0.648, CI = 0.52–0.76, p = 0.016), IGE (AUC = 0.701, CI = 0.56–0.83, p = 0.004), and also in differentiating TLE-HS patients with seizures from TLE-HS patients who had no seizures for 1 month prior to blood sampling (AUC = 0.624, CI = 0.51–0.73, p = 0.039).
