Rheumatoid neutrophilic dermatitis
General
- Case report rare manifestation of rheumatoid arthritis.[1]

Features:
- Nodular and diffuse pattern.
- Neutrophils - perivascular (without vessel wall injury).[1]

Rheumatic joint disease
- AKA joint with rheumatic disease.
General
Clinical:
- Tumour - swelling.
- Rubor - redness.
- Calor - heat.
- Dolor - pain.
Gross
Features:
- Pannus[2] - fibrovascular tissue or granulation tissue.
- Irregular surface - synovial hyperplasia.
- Subchondral cysts - involve the entire femoral head (late stage of disease).[3]
Note:
- Osteoarthritis subchondral cysts are associated with cartilage loss.[3]

Features:[5]
- Chronic inflammation, esp. lymphocytes.
- +/-Lymphoid follicles.
- Synovial hyperplasia - with papillary or polypoid architecture.
- Synoviocytes may show binucleation and mild atypia.
- +/-Fibrin.
- +/-Bone.
- +/-Cartilage.

RA may involve the lung.
Miscellaneous
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]
