[Diseases that affect both skin and oral mucosa].

BACKGROUND

Several diseases may affect both skin and oral mucosa. This article presents hereditary, autoimmune and other inflammatory conditions within this group.

MATERIAL AND METHODS

Review of the literature as well as the authors' own experience in the field.

RESULTS AND INTERPRETATION

Lichen planus, erythema multiforme and lupus erythematosus are relatively common disorders with generally favourable prognosis. The much less frequent bullous diseases pemphigoid and pemphigus are characterized by a high morbidity, often requiring a deliberate use of immunosuppressants. Stevens-Johnson syndrome, toxic epidermal necrolysis and the more severe forms of epidermolysis bullosa are potentially life-threatening conditions. It is recommendable that medical doctors and dentists are familiar with the clinical presentations and diagnostic procedures of diseases affecting skin and oral mucosa.
