Histology of rheumatoid nodule
In a rheumatoid nodule, scanning power view reveals a granulomatous tissue reaction pattern (Figure 1). Well formed necrobiotic granulomas form within the dermis frequently with deep extension (Figure 2). There is a surrounding palisade of histiocytes and a mixed infiltrate of lymphocytes, plasma cells, multinucleated giant cells and occasional eosinophils (Figure 3).
