Any area of the oral mucosas can be the site of PV lesions, mostly vesicles with consequent loss of the superficial epithelial layers.
Bullae are rare in the oral mucosa.
Most frequently affected are the soft palate, the gingiva and the border of the tongue. The gingival lesions worsen by tooth brushing. This photo from a 39 year-old woman with early PV shows marked generalized gingival erythema due to superficial erosion. This patient complained of a marked burning sensation especially while eating spicy foods. Cold, hot or alcoholic beverages will also induce marked discomfort.
