Sjögren syndrome, also Sjögren disease, is a disease that keeps rheumatologists busy. Sjögren is also spelled Sjoegren and Sjogren.
The syndrome may be part of another connective tissue disorder, e.g. rheumatoid arthritis, in which case it is called secondary Sjögren syndrome.[1]
General
Clinical - classically:
- Women in 50s.
- Dry mouth (xerostomia).
- Dry eyes (xerophthalmia).
Blood work:[2]
- ANA +ve.
- Anti-SSA (Ro) +ve.
- Anti-SSB (La) +ve.
Microscopic
Features (salivary gland):[2]
- Lymphocytic infiltration - key feature.
- Viable salivary gland or lacrimal gland acini.
- +/-Plasma cells.
- +/-Fibrosis.
DDx:
Note:
- Diagnosis is based on clinicopathologic correlation; the histology alone is insufficient.

Grading
Lesions can be graded with the Chisholm-Mason classification.[4] It is based on assessing 4 mm2 area of salivary gland tissue and depends on the abundance and aggregation of lymphocytes as follows:[5]
| Grade | Lymphocytes |
|---|---|
| 0 | absent |
| 1 | slight infiltrate |
| 2 | moderate infiltrate or less than one focus † |
| 3 | one focus † |
| 4 | more than one focus † |
† Focus = aggregrate of 50 lymphocytes.
Sign out
LOWER LIP, BIOPSY: - SQUAMOUS MUCOSA WITH PARAKERATOSIS. - SALIVARY GLAND WITH A MINIMAL LYMPHOCYTIC INFILTRATE, SEE COMMENT. COMMENT: Clinical and serologic correlation is required. The inflammation corresponds to Chisholm-Mason classification grade 3.
