Rheumatoid Nodule

Medical Definition: Subcutaneous nodules seen in 20-30% of rheumatoid arthritis patients. They may arise anywhere on the body, but are most frequently found over the bony prominences. The nodules are characterized histologically by dense areas of fibrinoid necrosis with basophilic streaks and granules, surrounded by a palisade of cells, mainly fibroblasts and histiocytes.
Guide Notes: in rheum arthritis; do not confuse with RHEUMATIC NODULE in rheum fever
