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 vitamin supplements only infrequently improve the ulceration. The relationship to vitamin B12 deficiency has been the subject of many studies. Although these studies found that 0–42% of those with recurrent ulcers suffer from vitamin B12 deficiency, an association with deficiency is rare. Even in the absence of deficiency, vitamin B12 supplementation may be helpful due to unclear mechanisms. Hematinic deficiencies can cause anemia, which is also associated with aphthous-like ulceration. Gastrointestinal disorders are sometimes associated with aphthous-like stomatitis, e.g. most commonly Celiac disease, but also inflammatory bowel disease such as Crohn's disease or ulcerative colitis. The link between gastrointestinal disorders
