Autoimmune bullous diseases (AIBD) are characterized by autoantibodies targeted against adhesion molecules, impairing their formation. According to localization criteria, pemphigus (intraepidermal blister and desmosomal involvement) and pemphigoid (subepidermal blister and dermoepidermal junction involvement) can be distinguished. In two-thirds of the cases, pemphigus vulgaris begins with oral lesions (mainly the buccal mucosa and palate, rarely the gingiva). Skin lesions are usual. Excepting paraneoplastic pemphigus (a recently individualized entity), oral lesions are uncommon in other types of pemphigus. Cicatricial pemphigoid mainly involves oral mucosa, frequently other mucous membranes, and rarely the skin. Gingival involvement is frequent. In case of desquamative gingivitis, the clip sign gives the diagnosis of cicatricial pemphigoid. Ocular involvement is frequent and causes blindness. Epidermolysis bullosa acquisita and IgA linear dermatosis are rare. Bullous pemphigoid and bullous lupus rarely involve the oral mucosa. Diagnosis of AIBD requires a biopsy within the mucosal membrane lesion for pathology examination and another biopsy in a lesion-free area for direct immunofluorescence detection of antibody fixation. Immunoelectron microscopy or immunoblast transfer may be needed for positive diagnosis. Corticosteroids are used to treat pemphigus and dapsone is used for cicatricial pemphigoid. Immunosuppressive therapy is rarely needed.

Mucous membrane pemphigoid (MMP) is an autoimmune blistering disease that predominantly affects the mucosa. We report eight patients with MMP who also had systemic lupus erythematosus (SLE), mixed connective tissue disease (MCTD), or both. Eight women (six white, two Hispanic; mean age of onset 53.5 years [range 44-68]) were studied. In four patients, both diseases were detected simultaneously, and in the other four patients, MMP preceded SLE or MCTD. MMP was widespread and resistant to conventional immunosuppressive therapy, but responded to intravenous immunoglobulin (IVIg). During a mean follow-up of 10.25 years (range 6-18), three patients had stable SLE/MCTD, whereas in the other five patients the SLE/MCTD required systemic corticosteroids either with or without immunosuppressive agents. Renal, serosal, pulmonary and neurological features were not observed in any patient. At the time of reporting, the MMP was in a prolonged sustained remission in all eight patients. The SLE/MCTD remained mild, did not involve vital organs and had continued with low-grade activity. In summary, we report the simultaneous occurrence of two rare diseases in a group of patients.

OBJECTIVE: Oral health and mucocutaneous inflammation might play an important role in the etiopathogenesis of many skin diseases, especially those that also involve the oral mucosa. This review examines the relationship between skin conditions and various oral health metrics to better understand how oral diseases, especially periodontitis, might influence the development or prognosis of several conditions, including aphthous stomatitis, atopic dermatitis, lichen planus, pemphigus, pemphigoid, and psoriasis. METHODS: Using the PubMed search engine between Summer 2017 and Summer 2018, searches were performed for: oral health OR oral hygiene AND psoriasis, eczema, dermatitis, hidradenitis suppurativa, acne inversa, pyoderma gangrenosum, Sweet's syndrome, neutrophilic dermatosis, subcorneal pustular dermatosis, hives, urticaria, cutaneous lupus, pemphigoid, pemphigus, or lichen planus OR aphthous stomatitis. The abstract of articles written in English were reviewed by the investigators and selected for inclusion if the study involved a correlation between oral health/hygiene and skin disease. After studies were included, the references were reviewed for additional relevant studies. Diseases listed in the search terms that were not ultimately discussed in this review did not produce any articles of relevance. RESULTS: Aphthous stomatitis is correlated with poor periodontal health and greater plaque accumulation. Atopic dermatitis shows an association with gingivitis, toothaches, and oral infections. Heavier enamel plaque burden and reduced oral care are implicated in the exacerbation of lichen planus. Mucous membrane pemphigoid and pemphigus are intimately influenced by oral health, underscoring the important role of good oral health and hygiene. Psoriasis presents a strong connection with oral streptococcal bacterial burden, has been shown to be improved or even cured with tonsillectomy, and has treatment outcomes that are generally associated with periodontal disease. CONCLUSION: Comorbid disease associations are frequently being reported in dermatology, spurring collaboration between multiple specialists and dermatologists. This review emphasizes a need for closer collaboration between dermatologists and dentists to treat several common skin diseases.
