Evaluation of CD20 in labial minor salivary gland biopsies in Sjogren’s syndrome

In H&E sections, FLS and FS were found only in the SjS patients and not in normal and inflammatory conditions. CD20 expression was found to be positive in 55% of SjS cases but negative in the normal and inflammatory groups. FS had been upgraded in IHC CD20 staining. FLS and FSs should be strictly evaluated according to the criteria. It was found only in SjS patients and not in normal and inflammatory conditions. Furthermore, CD20 can be used as an adjunct marker to decide the theranostic and prognostic markers of SjS. The results showed that criteria for scoring FS should be strictly followed and CD20 IHC can be used as a prognostic marker.
