To demonstrate the profile ofmucocutaneous lesions ofpSS and further explore their potential clinical significance, we perfermed a cross-sectional study on 874 patients. Methods： Demographic data, clinical manifestations, and laboratory results of 874 pSS patients were collected. Patients were divided into two groups according to the presence of mucocutaneous lesions. Differences in primary symptoms and systemic impairments between the two groups were analyzed. Results of laboratory tests were also compared alter excluding those who had taken corticosteroid from both groups. One-year follow-up was done, and occurrences of various new complications were compared. Results： Among the 874 pSS patients, 181 patients had mucocutaneous lesions, accounting for 20.7%. Multiple mucocutaneous manifestations were displayed, and the top four most common types of lesions were purpuric eruptions （39.8%）, urticaria （23.8%）, Raynaud＇s phenomenon （14.9%）, and angular stomatitis （9.9%）. Incidences of pulmonary interstitial fibrosis, pulmonary bullae, leukopenia, and anemia were significantly higher among patients with mucocutaneous lesions （P 〈 0.05）. Increase in lgG and decrease in C4 among patients with mucocutaneous lesions displayed statistical significance after excluding patients from both groups who had taken corticosteroid （P 〈 0.05）. Alter one-year follow-up, patients with mucocutaneous lesions presented a slightly higher incidence of new complications compared to those without. Conclusions： Mucocutaneous manifestations ofpSS patients were common and diverse. Patients with mucocutaneous manifestations had more systemic damages, higher level of IgG, and lower level of serum C4, suggesting a higher activity of the primary disease.展开更多
