Two cases of mucous membrane pemphigoid are presented. In the both cases bullae were formed on the gingivae only, with no involvement of the skin or other mucosa. They were diagnosed as mucous membrane pemphigoid by histopathogical findings and direct immunofluorescence technique. Topical steroids were effective. Both cases healed without scar formation, and there has been no recurrence. These findings suggest the existence of a variant type of mucous membrane pemphigoid that is limited to the oral mucosa and has a good prognosis.
