What is Oral Mucous Membrane Pemphigoid?

Mucous membrane pemphigoid (MMP), also called cicatricial pemphigoid, is a chronic autoimmune subepithelial blistering disease in which IgG and/or IgA autoantibodies target hemidesmosomal antigens (BP180, laminin-332, integrin alpha-6/beta-4) at the basement membrane.

Oral involvement is the most common manifestation, with painful blisters and erosions on the gingiva (desquamative gingivitis), buccal mucosa, palate, tongue, and lips. Other mucosae — conjunctiva (with risk of symblepharon and blindness), nasopharynx, larynx, esophagus, anogenital region — and skin can also be affected.

Diagnosis requires biopsy of perilesional mucosa for histopathology and direct immunofluorescence showing linear IgG and/or C3 at the basement membrane. Indirect IF and ELISA help characterize antigens. Treatment is long-term immunosuppression with multidisciplinary monitoring.

Symptoms

Painful gingival erosions and desquamation
Vesicles and blisters in the mouth
Difficulty eating, brushing teeth, and speaking
Eye redness, foreign body sensation, light sensitivity
Symblepharon (eyelid-eyeball adhesion)
Hoarseness or dysphagia (laryngeal/esophageal involvement)
Genital or anal blisters and scarring

Risk Factors

Older age (typically 60+)
Female sex slightly more affected
HLA-DQB1*0301 association
Coexisting autoimmune disease
Drug-induced cases (rare): furosemide, NSAIDs, ACE inhibitors
Chronic mucosal trauma
Family history rare

  • Persistent painful gum erosions
  • Recurrent oral blisters or vesicles
  • Eye redness or foreign body feeling with oral disease
  • Difficulty swallowing or hoarseness
  • Vision changes
  • Genital or anal blisters
  • No improvement on standard gingivitis therapy
