Rheumatoid arthritis, commonly abbreviated RA, is an autoimmune disorder.
Skin
General
- May manifest as rheumatoid neutrophilic dermatitis - super rare.[1]
Microscopic
Features:
- Nodular and diffuse pattern.
- Neutrophils.
Joints
Main article: Joints
Microscopic
Features:
- Chronic inflammation (e.g. lymphocytes).
Images:
Rheumatoid nodule
General
- Usually only in seropositive cases.[3]
Microscopic
- Necrotic collagen bundles with fibrin surrounded by:
- Palisading granuloma.
- +/-Eosinophils.
Notes:
- Histomorphologically very similar to Granuloma annulare.
DDx:
- Granuloma annulare - has mucin in the core of the granuloma.[4]
- Necrobiosis lipoidica.
Images:
- Rheumatoid nodule (granuloma.homestead.com).[5]
- Rheumatoid nodule (granuloma.homestead.com).[5]
- Rheumatoid nodule (utah.edu).[6]
Lung disease
- See Medical lung disease.
RA may involve the lung.
Amyloidosis
- See Amyloidosis.
Amyloidosis may be due to RA.
Felty syndrome
RA may occur in Felty syndrome -- the triad:[7]
- Rheumatoid arthritis.
- Splenomegaly.
- Neutropenia.
Felty syndrome is associated with large granular lymphocytic leukemia.[7][8]
