Solitary bulla on the soft palate - A case report

A number of vesiculobullous or vesiculoerosive diseases manifest in the oral cavity. These diseases vary in both frequency and severity. Vesicles are small, circumscribed, fluid-filled elevations that are round or ovoid and normally less than one centimeter in diameter. A bulla is similar to a vesicle except that it is larger than one centimeter in diameter. When vesicles and bullae rupture they leave secondary lesions known as crusts or erosions. Vesicles and bullae may occur singularly or they may occur in clusters that coalesce into larger lesions. Ulcerative lesions extend through the epithelium into the connective tissue, resulting in pain and possible scarring. Healing takes place with fibroblastic proliferation and scars usually form. Shallow craters that do not extend completely through the epithelium are called erosions. Erosions typically heal without any scar formation. In this article we present a case of a 35 year old man with a blister in the mouth.
