ObjectivesThe aim of this study was to find out the correlation and evaluate the accuracy of labial minor salivary gland biopsy as a diagnostic tool in the multidisciplinary management of patients with Sjögren syndrome.Materials And MethodsPatients, referred to our outpatient office between January 2014 and December 2018 from a rheumatologist for biopsy examination, as part of the complex diagnostic plan for suspected Sjögren syndrome, were included in the current study. Each specimen was examined histomorphometrically by the pathologist to calculate the focus score describing the degree of salivary gland inflammatory infiltration.ResultsFifty patients met the inclusion criteria. From the total number of patients, 39 presented with an established Sjögren syndrome by fulfilling the revised American-European criteria. From those, 27 had a positive lip biopsy. The remaining 12 patients from the total group, who were diagnosed with Sjögren syndrome based on the same criteria, had a negative lip biopsy.ConclusionThe labial minor salivary gland biopsy is a valuable diagnostic tool to establish the diagnosis of Sjögren syndrome. However, a positive biopsy result must always be correlated with all the other diagnostic criteria to prove the exact diagnosis (Tab. 1, Fig. 4, Ref. 49).
