Recurrent aphthous ulcers are the commonest form of stomatitis. The ulcers are shallow, erythematous, painful and last 4-14 days. The aetiology is unknown.

Stomatitis may accompany a more widespread pathology of the gastrointestinal system. Examples include:

  • Crohn's disease
  • ulcerative colitis
  • coeliac disease

Behcets syndrome is characterised by oral and genital ulceration.

Vitamin deficiency (e.g. niacin, riboflavin, folate and B12) may result in the combination of stomatitis and glossitis.

Acute leukaemia may cause stomatitis.
