Stomatitis (inside of the cheeks) or on the gingiva (gums). The condition resembles Oral lichen planus when biopsied. The diagnosis is made with Immunofluorescence techniques, which shows circulating and tissue-bound autoantibodies (particulate stratified squamous-epithelium-specific antinuclear antibody) to DeltaNp63alpha protein, a normal component of the epithelium. Treatment is with hydroxychloroquine. Terms such as "plasma cell gingivostomatitis", "atypical gingivostomatitis" and "idiopathic gingivostomatitis" are sometimes a synonym for plasma cell gingivitis, or specifically to refer to a severe form of plasma cell gingivitis. Stomatitis Stomatitis is inflammation of the mouth and lips. It refers to any inflammatory process affecting the mucous membranes of the
Aphthous stomatitis and keratinization. This subgroup often experiences remission during pregnancy. However, other studies report no correlation between aphthous stomatitis and menstrual period, pregnancy or menopause. Aphthous stomatitis is uncommon in people who smoke, and there is also a correlation between habit duration and severity of the condition. Tobacco use is associated with an increase in keratinization of the oral mucosa. In extreme forms, this may manifest as leukoplakia or stomatitis nicotina (smoker's keratosis). This increased keratinization may mechanically reinforce the mucosa and reduce the tendency of ulcers to form after minor trauma, or present a more substantial barrier to microbes and
