DOIAbstract
Our aim was to differentiate IgG4-related sialadenitis, primary Sjogren syndrome, and chronic obstructive submandibular sialadenitis by analysing clinical, radiographic, and pathological features. Fifty-five patients, 50, and 50 were enrolled, respectively and their baseline characteristics and serological, sialographic, and pathological findings compared. The male: female ratio for IgG4-related sialadenitis was 1: 1.2 for primary Sjogren syndrome 1: 15.7, and for chronic obstructive submandibular sialadenitis1: 0.92. Numbers with enlarged salivary glands were 55, 16, and 50; with xerostomia 26, 48, and 0; with a history of allergy 26, 4, and 6, and with coexisting systemic disease 12, 19, and 0 (p = 0.14). Mean (SD) serum IgG4 concentratio...
