Desquamative gingivitis

Desquamative gingivitis is a clinical finding with several potential etiologies. Among the most common are oral lichen planus, cicatricial pemphigoid, and pemphigus vulgaris, though various other differential diagnoses exist. The presence of desquamative gingivitis often results in poor oral hygiene, which can have downstream consequences, including periodontitis and tooth loss. Though certain mucosal findings may be suggestive of a particular diagnosis, a thorough history, physical examination, and appropriate dermato- and immunopathologic assessment is necessary for narrowing this broad differential diagnosis.

Zhou and colleagues detected ectopic lymphoid structures (ELS) that resemble tertiary lymphoid organs in pemphigus vulgaris and pemphigus foliaceous lesions. ELS were characterized by B cells reactive to the desmoglein 3 autoantigen, and were associated with active disease and B cell expansion. B cell differentiation in ELS was supported by the detection of centroblasts, plasmablasts, and plasma cells in these lesions. Chemokines that may induce B cell migration to pemphigus lesions were also detected in ELS.

Pemphigus is an autoimmune bullous disease characterized by IgG production against desmogleins. The major sites of autoantibody production are thought to be lymph nodes, spleen, and bone marrow. Previously, it has been suggested that autoreactive B cells might exist in the skin lesions in pemphigus and produce autoantibodies. In their report, Zhou et  al. expanded their previous studies and reported that ectopic lymphoid-like structures were found in pemphigus skin lesions, wherein B-cell differentiation and lesional B-cell expansion might progress.

Pemphigus is a chronic autoimmune blistering disorder, characterized by (muco-)cutaneous erosions due to autoantibodies against desmoglein 3 and/or 1. Pemphigus induction might be associated with drugs, malignancy or radiation therapy (RT); the latter being only rarely described. A rigorous literature review revealed around 30 cases of RT-associated pemphigus, which had been primarily treated with topical and/or systemic steroids, in some cases also dapsone or few other immunosuppressive agents were given. The most common underlying cancer type was breast cancer. We here present a 63-year-old male patient, who was pre-trea...

BackgroundDesquamative gingivitis (DG) is principally associated with erosive oral lichen planus (EOLP), mucous membrane pemphigoid (MMP), and pemphigus vulgaris (PV). MethodsSerum autoantibodies including antigastric parietal cell antibody (GPCA), antithyroglobulin antibody (TGA), and antithyroid microsomal antibody (TMA) were measured in 500 patients with DG, 287 EOLP without DG (EOLP/DG−) patients, and 100 healthy control subjects. ResultsThe 500 patients with DG were diagnosed as having EOLP in 455 (91%), PV in 40 (8%), and MMP in five (1%) patients. We found that 37.0%, 43.6%, and 42.6% of 500 patients with DG, ...

Desquamative gingivitis is the clinical term that most of times represents a gingival manifestation of mucocutaneous disease, in particular lichen planus, pemphigoid and pemphigus. It is characterized by an erythematous, friable and hemorrhagic gingiva, which can be accompanied by pain and burning sensation. An accurate diagnosis can be made on with careful history, clinical examination, light microscopic examination of gingival biopsy specimens, and immunophatologic and follow-up findings. The identification of the underlying disease is important to give an assertive therapeutical management.
