Oral Mucous Membrane Pemphigoid with Contact Dermatitis - A Rare Clinical Entity.

Mucous membrane pemphigoid (MMP) is a rare inflammatory, autoimmune, subepithelial vesiculobullous lesion. Oral mucosa is affected in almost 90% of cases. Its development is chronic with a possible involvement of ocular, laryngeal and genital mucosa. Spontaneous remission is rare. Currently, improving oral hygiene, topical corticosteroid treatment is used to control the oral lesions of MMP. In the present case report, a 53 year old female patient with a known history of hypothyroidism reported to the department of Periodontology with a complaint of burning sensation and tenderness in the gums on intake of spicy food for the past one week .The patient had also noticed the formation of blisters on the gums which would break off on their own. Hence provisional diagnosis of MMP was considered based on the clinical and histopathological examination which was later confirmed with immunofluorescent interpretations. The treatment objective is to suppress extensive blister formation, to promote healing, and to prevent scarring. The above objectives were met in our case by thorough periodontal maintenance and steroid therapy. She also presented with skin lesions due to contact dermatitis caused by occupational exposure to tobacco which makes this case report unique.
