What Histological Features Are Seen in Autoimmune Diseases?
Autoimmune diseases occur when the immune system mistakenly targets the body's own tissues. Histologically, this can be seen as lymphocyte infiltration, tissue necrosis, and specific patterns of tissue damage. Conditions like rheumatoid arthritis show pannus formation in joints, while in systemic lupus erythematosus, there may be deposition of immune complexes in the kidney, leading to glomerulonephritis.
