Our study aimed to determine the frequency of uveitis among MS patients through the Lyon MS Database and compare the clinical spectrum and time course of MS in patients with or without uveitis. Twenty-eight patients with uveitis were detected. The prevalence of uveitis in our population was 0.65% (28/4,300). Uveitis preceded onset of MS in 46% of the patients; it occurred simultaneously or after MS, in 18% and 36% of the cases, respectively. The topography and timing of uveitis were not associated with any significant difference in MS course and prognosis. There was no difference in the course and prognosis in patients with or without uveitis.

Although oral manifestations of sarcoidosis are unusual, physicians should be aware that this specific localization is frequently the first manifestation of the disease. Treatment modalities range from observation in asymptomatic patients to immunosuppressants for severe involvement.
