Lingual papillae depapillating oral conditions include geographic tongue, median rhomboid glossitis and other types of glossitis. The term glossitis, particularly "atrophic glossitis" is often used synonymously with depapillation. Where the entire dorsal surface of the tongue has lost its papillae, this is sometimes termed "bald tongue". Nutritional deficiencies of iron, folic acid, and B vitamins may cause depapillation of the tongue. Papillitis refers to inflammation of the papillae, and sometimes the term hypertrophy is used interchangeably. In foliate papillitis the foliate papillae appear swollen. This may occur due to mechanical irritation, or as a reaction to an upper respiratory tract infection. Other
Inflammation the lysosomal elimination of the infective agent. Specific patterns of acute and chronic inflammation are seen during particular situations that arise in the body, such as when inflammation occurs on an epithelial surface, or pyogenic bacteria are involved. Inflammatory abnormalities are a large group of disorders that underlie a vast variety of human diseases. The immune system is often involved with inflammatory disorders, demonstrated in both allergic reactions and some myopathies, with many immune system disorders resulting in abnormal inflammation. Non-immune diseases with causal origins in inflammatory processes include cancer, atherosclerosis, and ischemic heart disease. Examples of disorders associated with
