title: [Oral medicine 11. Red and blue lesions of the oral mucosa].
abstract: A red or blue mucous membrane disorder of the oral cavity can arise in response to a local cause of irritation, as a cause of an inflammation reaction to an infection, an auto-immune reaction to a local factor, and as an expression of an underlying systemic disorder. Moreover, it can be an expression of a premalignant or malignant mucous membrane disorder. Knowledge about and recognition of the different red and blue mucous membrane disorders can hasten the diagnosis and possible treatment. In the case of a premalignant (erythroplakia) or a malignant mucous membrane disorder (squamous cell carcinoma), the prognosis is better with early diagnosis and treatment than at a later stage of the disease.
