Introduction: Vascular events account for a considerable burden of morbidity and mortality in Behçet syndrome (BS). Thrombosis occurs in 1.8–21 % pediatric BS patients, even if the real prevalence is still largely unknown. Objectives: To report clinical features and outcomes of pediatric BS patients with thrombosis and to compare the demographic and clinical characteristics of BS patients with and without thrombosis. Methods: Retrospective data collection of BS patients with thrombosis (T+) included in the EUROFEVER registry. BS patients without thrombosis (T-), belonging to the same rheumatology units, were matched in a 2:1 ratio. Results: 37 T+ were compared to 74 T- patients. At onset, ICBD criteria fulfillment was higher in the T- group (p = 0.015). Caucasian patients were more often T-, Turkish patients were more frequent in T+ group (p = 0.002). At onset, pustulosis was most frequently observed in the T- (p < 0.001) as well as gastrointestinal symptoms (p < 0.001) and ocular involvement (p = 0.022). Neurological symptoms were more often described in T+ (p = 0.034). As for T+, thrombosis was reported at BS presentation in 8/37 (21.6 %). For the T + e patients who developed thrombosis later, oral aphthosis (p = 0.003), genital aphthosis (p = 0.014) were more frequently observed at BS onset, while pustulosis (p = 0.005) and fever (p = 0.043) coexisted with thrombosis. Thrombosis was mainly venous (26/37,70.3 %), involving the cerebral sinuses (21/37, 56.8 %). After thrombosis, 35/37 (94.6 %) T+ patients received an immunomodulatory treatment compared with 16/29 (55.2 %) pre-thrombosis. A recurrence was reported in 6/31(19.4 %). Conclusion: Thrombosis was reported at BS presentation in one fifth of cases. Pustolosis and fever were more frequently concomitant to thrombosis. Sinus veins were the most frequent site.
