Histopathological assessment of salivary gland biopsies is an important element of the diagnostic work-up of Sjögren's syndrome (SS) (Fox, 2017; Kroese et al., 2018). Microscopic evaluation of salivary glands of primary SS (pSS) patients reveals characteristic periductal lymphocytic infiltrates (foci), which mainly consist of T- and B-lymphocytes, as well as a variety of non-lymphoid cells, including dendritic cells and macrophages. Over time, these infiltrates may become organised to ectopic lymphoid tissue with T/B cell compartmentalisation, presence of CD21+ follicular dendritic cell (FDC) networks and high endothelial venules (Fisher et al., 2017; Kroese et al., 2014; Kroese et al., 2018; Salomonsson et al., 2003).
