What Are Some Common Inflammatory Disorders and Their Histological Features?
Several inflammatory disorders can be identified histologically. For example, in rheumatoid arthritis, synovial membrane inflammation is prominent, with infiltration by lymphocytes and plasma cells, and pannus formation. In inflammatory bowel disease (such as Crohn's disease and ulcerative colitis), the histological features include crypt abscesses, granulomas, and transmural inflammation. In asthma, there is chronic inflammation of the airways with eosinophils, mast cells, and T lymphocytes, along with mucus gland hyperplasia and smooth muscle hypertrophy.
