What Can Histology Reveal About Autoimmune Diseases?
Autoimmune diseases such as rheumatoid arthritis and lupus erythematosus show distinct histological features. For example, in rheumatoid arthritis, synovial biopsy may reveal pannus formation, chronic inflammation, and lymphoid aggregates. Lupus erythematosus, on the other hand, may show characteristic lupus nephritis with "wire loop" lesions in the kidneys due to immune complex deposition.
