A 93 year old female presented with oral pain and difficulty in wearing her dentures, of two months’ duration. Oral examination revealed superficial ulcers bilaterally on the buccal mucosae and hard palate (fig. 1). The provisional diagnosis included benign mucous membrane pemphigoid, pemphigus vulgraris and paraneoplastic pemphigus. An incisional biopsy was performed. Histological examination showed a subepithelial bullous formation (fig. 2).
