Acute synovitis is an inflammatory process involving the synovium.
This article deal with nonspecific causes of acute synovitis (acute nonspecific synovitis).
General
- Cultures negative - by definition.
- Nonspecific finding.
- May form a tumour-like mass.[1]
Microscopic
Features:
- Synovium with abundant neutrophils.
- No significant number of plasma cells.
DDx:
- Infectious synovitis.
- Rheumatoid arthritis - should have plasma cells.
Images
AS - low mag.
AS - intermed. mag.
AS - high mag.
AS - very high mag.
