BOF 87
Pathology of rheumatoid arthritis, all are true,
except:
1-the earliest change is swelling and congestion of
the synovial membrane and the underlying connective tissue
2-the infiltrating T lymphocytes are mainly CD8
positive cells
3-subcutaneuos nodules consist of central fibrinoid
necrosis surrounded by palisading mononuclear cells
4-the muscles adjacent to the inflamed joints atrophy
and there may be a low grade lymphocytic myositis
5-effusions into the joints are mainly seen in active
disease
