Glossitis to pernicious anemia, they are now used as synonyms for atrophic glossitis generally. In this article, the term glossitis, unless otherwise specified, refers to atrophic glossitis. Candidiasis may be a concurrent finding or an alternative cause of erythema, burning, and atrophy. This condition is characterized by a persistent erythematous, rhomboidal depapillated lesion in the central area of the dorsum of the tongue, just in front of the circumvallate papillae. Median rhomboid glossitis is a type of oral candidiasis, and rarely causes any symptoms. It is treated with antifungal medication. Predisposing factors include use of corticosteroid sprays or inhalers or immunosuppression.
Inflammation hypersensitivity, is the result of an inappropriate immune response triggering inflammation, vasodilation, and nerve irritation. A common example is hay fever, which is caused by a hypersensitive response by mast cells to allergens. Pre-sensitised mast cells respond by degranulating, releasing vasoactive chemicals such as histamine. These chemicals propagate an excessive inflammatory response characterised by blood vessel dilation, production of pro-inflammatory molecules, cytokine release, and recruitment of leukocytes. Severe inflammatory response may mature into a systemic response known as anaphylaxis. Inflammatory myopathies are caused by the immune system inappropriately attacking components of muscle, leading to signs of muscle inflammation. They may
