Minor salivary gland evaluation: Sjögren's syndrome.

Results: For 22 of the 69 patients, all 3 sections were scored at <1 and interpreted as inconclusive for the presence of SS. For 20 cases, all 3 sections were scored at ≥1 and interpreted as diagnostic for SS. In the remaining 27 cases, the score was found to vary between sections. Plasma cell foci were observed in 11 cases, with 5 cases exhibiting a PFS of ≥1. Of those 5 cases, 4 also had a LFS of ≥1. Conclusion: Assessment of 3 serial sections in MSGB has the potential to improve accuracy of SS diagnosis by detecting specific features that may not have been detected in a single section. We concluded that data about the PFS require further evaluation.
