Erythema (Ancient Greek: ἐρύθημα, from Greek erythros 'red') is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. [1] It occurs with any skin injury, infection, or inflammation .
The disease occurs on the bone-bound oral mucosa of the hard palate and alveolar ridges. Inflammatory papillary hyperplasia is usually asymptomatic. It presents as a cluster of individual papules or nodules that may be erythematous, somewhat translucent, or normal in surface coloration. Mucosa is erythematous and has a pebbly or papillary surface.
The lesion is usually symmetric, well demarcated, erythematous and depapillated, which has a smooth, shiny surface. Less typically, the lesion may be hyperplastic or lobulated and exophytic. There may be candidal lesions at other sites in the mouth, which may lead to a diagnosis of chronic multifocal oral candidiasis. Sometimes an approximating ...
Initially, the corners of the mouth develop a gray-white thickening and adjacent erythema (redness). [2] Later, the usual appearance is a roughly triangular area of erythema, edema (swelling) and breakdown of skin at either corner of the mouth. [2] [4] The mucosa of the lip may become fissured (cracked), crusted, ulcerated or atrophied.
Reticular erythematous mucinosis (REM) is a skin condition caused by fibroblasts producing abnormally large amounts of mucopolysaccharides. It is a disease that tends to affect women in the third and fourth decades of life.
Desquamative gingivitis is an erythematous (red), desquamatous (shedding) and ulcerated appearance of the gums. [1] It is a descriptive term and can be caused by several different disorders. [ 2 ]
The appearance of the involved mucosa is erythematous (red) and edematous (swollen), [4] sometimes with petechial hemorrhage (pin-points of bleeding). [1] This usually occurs beneath an upper denture. Sometimes angular cheilitis can coexist, which is inflammation of the corners of the mouth, also often associated with Candida albicans.
Erythema multiforme (EM) is a skin condition that appears with red patches evolving into target lesions, typically on both hands. [2] [3]It is a type of erythema possibly mediated by deposition of immune complexes (mostly IgM-bound complexes) in the superficial microvasculature of the skin and oral mucous membrane that usually follows an infection or drug exposure.
